The main purpose

Trimethylolpropane is an important fine chemical product, and it is a commonly used chain extender in the resin industry. It has a low melting point and three methylol groups in its molecular structure. It can react with organic acids to form monoesters or multiple esters, react with aldehydes and ketones to form acetals and ketals, and react with diisocyanates to form carbamates.

Products are mainly used in alkyd resins, polyurethanes, unsaturated resins, polyester resins, coatings and other fields. They can also be used to synthesize aviation lubricants, plasticizers, surfactants, wetting agents, explosives, printing inks, etc. Used as textile auxiliaries and heat stabilizers for polyvinyl chloride resin.
