my country's polyurethane industry started in the late 1950s and has now become the largest producer and consumer of polyurethane. At present, my country's polyurethane production is regionally concentrated, and has formed four regions: the Yangtze River Delta centered on Shanghai, the Pearl River Delta centered on Guangdong, the Bohai Rim and the Northeast region centered on Huludao, and the Northwest region centered on Lanzhou. In the future, the southwest region centered on Chongqing and the Hercynian region centered on Quanzhou will be added in the future. As the industry develops, many problems have emerged, such as overcapacity, few high-end products, and serious product homogeneity. These problems have seriously affected the international competitiveness of my country's polyurethane industry and need to be resolved urgently. Polyurethane (PU) is an organic polymer product produced by the chemical reaction of isocyanate and active hydrogen. Its properties can be adjusted in a wide range, such as from sponge to elastomer, from paint to sealant, from shoe sole slurry to spandex and more. 1. The status of the international polyurethane industry 1.1 Development History of International Polyurethane Industry In 1937, German Otto Bayer first discovered that polyurethane could be produced by the addition polymerization of polyisocyanates and polyol compounds. After World War II, the United States, Britain, Japan and other countries introduced German technology for the production and development of polyurethane. In 1945, the American Dupont Company and Monsanto Company built a 2,4-toluene diisocyanate test workshop for the production of rigid polyurethane foam. In 1946, the United States carried out research on rigid polyurethane foam, and the products were used in aircraft sandwich panels. In 1952, Bayer conducted a pilot test of polyester-based flexible polyurethane f

2. Domestic polyurethane industry status 2.1 Development history of domestic polyurethane industry my country's polyurethane industry started late in the late 1950s. In 1958, Dalian Dyestuff Factory developed isocyanate (TDI), and in 1962, it built a production facility with an annual output of 500 tons. In the early 1960s, Jiangsu Chemical Industry Research Institute and others developed polyether-type PU flexible foam. In the early 1970s, Jiangsu Research Institute and Nanjing Rubber Factory developed mixed PU elastomer (MPU). At the same time, Tianjin Chemical Industry Research Institute and Tianjin Paint Factory developed PU coatings. In 1974, Beijing Institute of Construction Engineering developed PU waterproof material, and Jiangsu Institute developed PU waterproof and grouting materials. In 1976, Jiangsu Research Institute and others carried out the research and development of PU track rubber technology, and in 1978, it began to promote it on a large scale in domestic sports venues. In the 1980s, domestic manufacturers successively introduced 10,000-ton polyether production equipment. For example, Yantai Synthetic Leather Factory introduced PU synthetic leather technology from Japan and a 10,000-ton MDI production equipment. In the 21st century, the polyurethane industry has become one of the fastest growing industries in my country's chemical industry. 2.2 Domestic production and sales of polyurethane The output of my country's polyurethane industry from 2014 to 2021 is shown in Figure 4. It produced 966 tons in 2014, 10.35 million tons in 2015, 10.85 million tons in 2016, and 11.89 million tons in 2017, maintaining a compound annual growth rate of 7.28%. The output in 2020 will be approximately 14.7 million tons, a year-on-year increase of 7.6%, and will reach 15.32 million tons in 2021, a year-on-year increase of 4.22%. my country's polyurethane consump

1) Polyurethane foam Polyurethane foam is widely used in thermal insulation, furniture production, etc. According to data from Allied Market Research, my country's polyurethane foam (including flexible foam and rigid foam) sales volume was 1.3783 million tons in 2019, and is expected to reach 1.6526 million tons in 2022, with an average annual compound growth rate of 6.24% from 2019 to 2022. The guidance of the "Thirteenth Five-Year Plan" development plan for the plastics processing industry points out that the "import substitution" strategy should be vigorously implemented to strive for the main products and accessories of the plastics processing industry to meet the needs of economic and social development, especially the high-end fields, by 2025. Some products and technologies have reached World leading level. 2) Polyurethane elastomer Polyurethane elastomers are divided into casting type, thermoplastic type and mixing type according to the production process. They are widely used in steel, conveyor belts, papermaking rubber spokes and other fields. In recent years, the proportion of polyurethane elastomers in polyurethane products in my country has been increasing. In 2015, the consumption of polyurethane elastomers was 860,000 tons, a year-on-year increase of 4.2%. In 2018, it rose to 1.07 million tons. The consumption continued to increase from 2019 to 2022. The reason is mainly due to the large-scale use of thermoplastic elastomers in the automotive field and the construction industry. (TPE) materials have driven the development of the industry. 3) Polyurethane coating In 2015, the consumption of polyurethane coatings was about 1.65 million tons, accounting for 16% of the sales volume of polyurethane products. In 2021, it will reach 2.45 million tons, accounting for about 16%. At present, there are more than 60 kinds of polyurethane coatings, and the production enterprises ar

Source - Global Polyurethane Network According to reports, the European polyurethane market value is expected to reach US$26.24 billion by 2024. The rising demand for sustainable building materials has become an important driving force for the development of the industry. The development of terminal industries such as construction, automobiles, transportation, furniture and bedding is the main driving force of the polyurethane industry. It is expected that the continuous development of the construction industry will be the main driving force. The construction industry in Eastern European countries such as Hungary, Poland, and Slovakia will have great development, thereby driving the rise in demand for rigid polyurethane foam. Rigid foam consumes the most, accounting for 30% of the European market in 2015. Financial incentives to reduce energy consumption will promote the development of rigid foam. In 2015, the European polyurethane market size was 4.91 million tons, and it is expected to reach 6.9 million tons in 2024, with a compound annual growth rate of 3.8%. Polyurethane is the most consumed in the construction industry, accounting for more than 35% of the total in 2015. It is expected that the electrical appliance field will have the largest growth, at 5.3%. Germany had the largest demand for polyurethane in 2015, accounting for an estimated 17.5% of the market share. As a major automobile production and export country, Germany has the largest demand for rigid foam. In 2015, the demand for rigid foam accounted for 30% of polyurethane.

01 Overview of polyurethane foam Polyurethane foam is a porous polyurethane material composed of a large number of micropores and polyurethane resin porous wall meridians, also known as "PU foam", which is the largest variety of polyurethane products, accounting for more than 50% of the total amount of polyurethane products. PU foam accounts for about 55% of the total polyurethane products in Europe, about 65% in Asia and about 70% in the United States. In the market share of various types of foam plastics, PU foam accounts for more than 50%. Compared with other foam materials, polyurethane foam has many characteristics in performance, due to the different production processes and adjustable formulation components, polyurethane can be made into many different varieties of foam. The rapid development of domestic refrigeration and insulation, building energy saving, solar energy industry, automobiles, furniture and other industries has greatly driven the demand for polyurethane foam. In the field of insulation materials, polyurethane foam has occupied a solid market position. Polyurethane foam is divided into soft and rigid types, and with the changing market situation, the demand for polyurethane foam is also increasing, which brings good opportunities. 02 Rigid polyurethane foam Polyurethane rigid foam is mostly closed-cell structure, which has excellent characteristics such as good thermal insulation effect, light weight and convenient construction. At the same time, it also has the characteristics of sound insulation, shockproof, electrical insulation, heat resistance, cold resistance, solvent resistance, etc., and is widely used in refrigerators, freezer box insulation layer, cold storage,

New regulations coming on August 24, 2023, requiring construction training for materials containing diisocyanates, have raised concerns about polyurethane adhesives. These materials are widely used in industrial facilities to bond metals, plastics and even glass due to their reasonable cost, good adhesion, high peel strength and good impact resistance. Polyurethanes can be used to make rigid and flexible foams, as well as varnishes and coatings, adhesives, potting compounds and fibers. The most common use of polyurethane is foam, which accounts for about two-thirds of the total amount of polyurethane used. About 6% of the world's polyurethane is used in adhesives and another 3% in sealants. Polyurethane adhesives are available in one-component (1K) and two-component (2K) formulations, and the basic chemical reaction is the same for both types. They are usually thermosets, but there is another type of polyurethane thermoplastic hot melt adhesive, which is usually polyester-based. Advantages of polyurethane adhesives Polyurethane adhesives have excellent adhesion to a wide range of materials – they bond plastics, metals and synthetics well. Polyurethane adhesives have lower surface energy than epoxy adhesives and therefore have better wetting and adhesion to plastic substrates. There are many types of polyurethane adhesives – they can be formulated with different cure lifetimes, while viscosity grades can range from self-leveling to non-slumping and curing grades from very soft to very hard. Polyurethane adhesives have good performance characteristics: extremely toughness, high peel strength, suitable for gap filling. Because they are impact, solvent, weather and abrasion resistant, they are popular in outdoor applications. Importantly, they are relatively low-cost materials that are easy to apply and cure (typically, these adhesives cure at room temperature, but heating speeds up the c

According to the World Economic Forum, the fashion industry and its supply chain emit 10% of the world's greenhouse gases each year. As footwear companies begin to consider their environmental footprint, brands are finding that a significant portion of their greenhouse gas emissions come from the materials they use (from carbon-intensive petrochemicals). Evoco was founded by Jason Robinson, a pioneer in climate technology with over 20 years of experience in commercializing renewable technologies. Evoco is an innovative company dedicated to unlocking the potential of phytochemistry to develop low-carbon, high-performance materials. Commenting on Evoco's significant impact on the footwear industry, Jason Robinson said: "The footwear industry has assessed its environmental impact and now understands that the main way to reduce its environmental impact is to reduce its dependence on petrochemicals. Evoco's solution is to put plants at the heart of its innovation platform, replacing oil with plants to develop high-performance materials. Helping brands on their depetrochemical journey by providing solutions that decarbonize and detoxicate their supply chains." In fact, Evoco's plant-based foam technology FATES is made from up to 85% bio-based components, 100% of which are plant-based certified. Using bio-based foam to manufacture footwear components such as insoles or midsoles can reduce greenhouse gas emissions by up to 70% compared to traditional petroleum-based polyurethane foams. Notably, the company regularly conducts life cycle analyses to drive innovation and product development to minimize environmental impact. The company focuses on all impact categories, not just greenhouse gas emissions. Jason Robinson acknowledges that standard polyurethane foam has many advantages, but says FATES performs as well as these petroleum-based components, if not better. For consumers, this means a high-quality, sustainable pro

What is exterior polyurethane spraying? At this stage, how do China's construction enterprises carry out exterior wall polyurethane spraying and coating, and what is the basic situation? The following is the content related to the professional architectural terminology of polyurethane spraying construction of the exterior wall, and the basic situation is as follows: Basic overview of polyurethane spraying for exterior walls: Polyurethane rigid foam roof, exterior wall waterproof insulation integrated system After the building structure is roofed, the insulation and waterproofing of the roof is a very important project. Traditional practice insulation and waterproofing are two systems, each of which is constructed, and the superposition of the two materials constitutes a waterproof insulation system for the roof. In the actual construction project, due to the influence of a variety of factors, there are often some quality problems, resulting in damage to the building, thereby destroying the waterproof insulation system of the roof. Polyurethane spraying exterior wall insulation construction process: 1. The ambient temperature during spraying construction should be 10-40 degrees, the wind speed should not be greater than 5m/s (level 3 wind), the relative humidity should be less than 80%, and no construction should be carried out in rainy days. When the construction environment temperature is lower than 10 degrees, reliable technical measures should be adopted to ensure the spraying quality. 2. The distance between the spray gun head and the working surface should be adjusted according to the pressure of the spraying equipment, and should not exceed 1.5m; the speed of the spray gun head should be uniform during spraying. During the operation, it is necessary to confirm that the surface of the polyurethane rigid foam sprayed on the previous layer does not stick to the hands before spraying th

Abu Dhabi National Oil Company (Adnoc) and Austrian Oil and Gas (OMV) are discussing merging Borouge and Borealis to form a chemical giant valued at more than $30 billion. OMV holds a 75% stake in Vienna-based Borealis, Austria, with ADNOC holding the remainder. Borouge, listed in Abu Dhabi, UAE, is a joint venture between ADNOC and Borealis with a market capitalization of approximately $22 billion. According to Bloomberg recently, the owners of the two companies are discussing the potential value and ownership structure of the combined company, and may agree on formal terms of the merger in the coming weeks. Borealis, including its stake in Borouge, is reportedly valued at about $10 billion. The combined entity's total valuation could exceed $30 billion (including potential synergies). The source added that the talks have been on and off for several months and there is still a possibility that they could be delayed or stopped. They noted that the two fundamental obstacles to reaching any agreement were specific value and ownership structures. However, given a number of factors, including government regulation, the final agreement may not be reached. The merger will give Adnoc and OMV the scale advantage they need to compete, simplifying the ownership structure. At the same time, it gives them more freedom to spend and grow in Asia, where demand for chemicals and plastics is currently rising. Borealis, a leading producer of polyolefins and basic chemicals in Europe, generated total revenues of around €12.2 billion and a net profit of €2.1 billion in 2022. Borouge's 2022 revenue was $6.7 billion and full-year adjusted EBITDA was $2.6 billion. Thermoplastic Polyurethane (TPU) is a type of elastomer

Polyurethane is an important new chemical material, known as the "fifth largest plastic" because of its excellent performance and variety of uses. China's polyurethane industry has gradually developed and grown with the 100-year history of the founding of the CPC. Today, from furniture, clothing, to transportation, construction, to aerospace and national defense construction, the ubiquitous polyurethane materials not only represent the level of innovation of the modern chemical industry, but also become an important support for China's construction of a manufacturing power. China's polyurethane industry began in the late 50s and early 60s of last century, starting from the production of polyurethane raw materials. In 1958, Dalian Dye Factory took the lead in successfully developing toluene diisocyanate (TDI), and in 1968 built a production plant with an annual output of 500 tons, which created conditions for the development of China's polyurethane industry. Subsequently, Jiangsu Chemical Research Institute and other units have successively developed polyether PU flexible foam plastics, mixed PU elastomers (MPU), polyurethane coatings, polyurethane waterproof materials and other products. In 1976, the Department of Chemical Industry of Jiangsu Province organized Jiangsu Chemical Research Institute and other units to carry out technical research on polyurethane runway glue, and in 1978 began to promote and apply various types of sports venues in China. After the reform and opening up, China began to introduce foreign advanced TDI production technology and equipment. In 1983, the former Ministry of Light Industry invested and built an annual output of 10,000 tons of diphenylmethane diisocyanate (MDI) and TDI project in Yantai, Shandong Province. After the 80s of the 20th century, China began to introduce foreign advanced polyurethane raw materials and products production technology and equipment, domestic scientific research

The regional distribution pattern of domestic polyurethane has gradually formed six major plates, of which the Yangtze River Delta region centered on Shanghai, polyurethane raw materials and their products in the region have accounted for half of the country. The Yangtze River Delta region leads the world in MDI production capacity The Yangtze River Delta region centered on Shanghai is currently the most developed area in the domestic PU industry, and PU raw materials and their products have accounted for more than half of the country. Among them, MDI production capacity accounts for the vast majority of the country's total production capacity, and has become one of the largest MDI production capacity regions in the world. In 2021, Covestro increased MDI production capacity by 50,000 tons; Wanhua Chemical expanded the capacity of the existing Ningbo MDI plant, expanding the capacity of the first phase MDI plant from the existing 400,000 tons/year to 600,000 tons/year, and the second phase of the MDI plant from the existing 800,000 tons/year to 1.2 million tons/year, and it is expected that the two projects will achieve capacity contribution around 2023-2024. Specifically, there are four major production bases in the Yangtze River Delta region, namely Shanghai Polyurethane Industrial Park, Zhejiang Ruian Huafeng Industrial Park, Huafeng New Material Industrial Park and Ningbo Daxie Island MDI Industrial Park. The listed enterprises of polyurethane in the Yangtze River Delta have strong strength and a large scale of production and sales There are many listed enterprises in the polyurethane industry in the Yangtze River Delta region, sitting on leading enterprises such as Huafon Chemical, Kangda New Materials, Huide Technology, Oriental Materials and Meisde, with a large production and sales layout.

Polyurethane (PU) is an organic polymer product produced by the chemical reaction of isocyanate and active hydrogen, and its properties can be adjusted in a wide range, such as from sponge to elastomer, from paint to sealant, from shoe sole slurry to elastic fiber. China's polyurethane industry began at the end of the 50s of the 20th century and has now become the largest producer and consumer of polyurethane. At present, China's polyurethane production is in a regional concentration trend, has formed Shanghai as the center of the Yangtze River Delta, Guangdong as the center of the Pearl River Delta, Huludao as the center of the Bohai and Northeast region, Lanzhou as the center of the northwest region of four plates, in the future to increase the southwest region centered on Chongqing and Quanzhou centered on the Haixi region plate. At the same time of the development of the industry, there have been many problems, such as overcapacity, few high-end products, and serious product homogenization. These problems have seriously affected the international competitiveness of China's polyurethane industry and need to be solved urgently. 1 International polyurethane industry status 1.1 Development history of international polyurethane industry In 1937, Otto Bayer in Germany first discovered that polyisocyanates and polyol compounds can be polyformed to produce polyurethane. After World War II, the United States, Britain, Japan and other countries introduced German technology for the production and development of polyurethane. In 1945, the American company Dupont and Monsanto company built a pilot plant of 2,4-toluene diisocyanate to produce rigid polyurethane foam. In 1946, the United States carried out research on rigid polyurethane foam, and the products were used in aircraft sandwich panels. In 1952, Bayer company carried out the pilot test of polyester flexible polyurethane foam, and in 1952~1954, it develo
