Polyol Production Line Turnkey Project | JCT Machinery

What is polyol?

Polyols are organic compounds containiing multiple hydroxyl (-OH) groups and are one of the important raw materials for polyurethane production. They are mainly used to make foam plastics, elastomers, coatings, adhesives and sealants, and are widely used in industries such as construction, automobiles, furniture, footwear and electronics.
