Uses

Rubber field: Trimethylolpropane Trimethacrylate is used as a vulcanization activator for special rubbers such as EPDM and EPDM, which can shorten the vulcanization time, increase the degree of vulcanization, and improve the mechanical strength and wear resistance of the product.
Plastic field: It is used for cross-linking modification of thermoplastics such as polyethylene and polyvinyl chloride, which can improve the heat resistance and solvent resistance of the product.
Other fields: It can be used as a modifier for alkyl acrylates and polyester resins; used in coatings and adhesives to shorten the curing time; used to prepare insulating materials for microelectronic products and special ion exchange resins; and can also be used as an impact modifier and copolymer modified monomer.
