Polyester Polyol

Polyester polyols are the important raw materials of coating, adhesives, elastomer and foam.
Polyester polyols can be divided into aromatic polyols and aliphatic polyols because of the acid and polyols. 
Aromatic polyols are mostly used in preparing PU rigid foam which foam has great thermal insulation ability. 
Aliphatic polyols with different raw materials show different performance. 

No mater aromatic polyols or aliphatic polyols, we can provide the special products according to customers` requirement.    

Polyester Polyol is a type of polyol that is derived from the reaction between a polyol (such as glycerol or ethylene glycol) and a dicarboxylic acid (such as adipic acid or phthalic anhydride). It is commonly used as a raw material in the production of polyurethane foams, coatings, adhesives, and elastomers.

Polyester polyols have several advantages over other types of polyols. They have good chemical resistance, mechanical properties, and thermal stability. They also have low toxicity and are environmentally friendly. Additionally, polyester polyols can be easily modified to achieve desired properties, such as increased flexibility or flame retardancy.

Polyester polyols are typically liquid at room temperature and have a high molecular weight. They can be further reacted with isocyanates to form polyurethane materials, which have a wide range of applications in various industries, including automotive, construction, and furniture.
