Polyurethane prepolymers are made by reacting diisocyanates and polyols under controlled conditions. They are used to produce various forms of polyurethane including rigid and flexible foams, coatings, adhesives, sealants, and elastomers. Rigid polyurethane foams are mainly used for thermal insulation in construction applications owing to their high insulation and low conductivity properties. Flexible slabs of polyurethane foams are used in mattresses, furniture, automotive interiors ... Read more

Polyurethane Prepolymers: An Essential Raw Material for Manufacturing Industries

What are Polyurethane Prepolymers?
Polyurethane prepolymers, also known as isocyanate terminated prepolymers, are polyols that have been reacted with diisocyanates but terminated with residual isocyanate groups. They are highly viscous resins synthesized by reacting a polyol such as polyether polyol or polyester polyol with a diisocyanate like MDI or ... Read more
