Application

Trimethylolpropane is an important fine chemical product that is commonly used in the resin industry as a chain extender. The melting point is low, and there are three methylol groups in the molecular structure, which can react with organic acids to form monoesters or polyesters, react with aldehydes and ketones to form acetals and ketals, and react with diisocyanates to form carbamates.

The products are mainly used in the fields of alkyd resins, polyurethanes, unsaturated resins, polyester resins, coatings, etc., and can also be used in the synthesis of aviation lubricating oils, plasticizers, surfactants, wetting agents, explosives, printing inks, etc. Used as a thermal stabilizer for textile auxiliaries and polyvinyl chloride resins.
