N,N’－m－phenylene dimaleimide is a multifunctional rubber auxiliary, which can be used as vulcanizing agent, co-curing agent of peroxide system, anticoking agent and viscosity builder in rubber processing, and it is suitable for both general-purpose rubber, special rubber and rubber-plastic parallel system.

In natural rubber, with sulfur, it can prevent the return of vulcanization, improve heat resistance, reduce heat generation, aging resistance, improve the adhesion between rubber and cord and the modulus of vulcanized rubber. Used in shoulder rubber of loaded tires, cushion layer and other rubbers, it can solve the problem of shoulder emptying of bias loaded tires, and can also be used in large-size and thick products of natural rubber and all kinds of rubber miscellaneous products.

In neoprene rubber, chlorosulfonated polyethylene rubber, styrene butadiene rubber, nitrile rubber, isoprene rubber, butyl rubber, bromobutyl rubber, acrylate rubber, silicone rubber and rubber-plastic rubber and other special rubbers, as an auxiliary vulcanizing agent, it can significantly improve the crosslinking performance, improve heat resistance, suitable for high temperature vulcanization system, reduce the permanent deformation of the compression is very obvious, but also reduce the dosage of peroxides, to prevent rubber from burning during processing. It can also reduce the amount of peroxide, prevent the rubber from burning in the process, and improve the adhesive strength of rubber, cord and metal.

HVA-2 is a non-sulfur vulcanizing agent, used in cable rubber, it can replace all sulfur-containing vulcanizing agents such as thiazole, thiuram, etc., which solves the problem of blackening of copper conductors and copper electrical appliances due to contact with sulfur-containing sulfurizing agents to generate sulfurized copper contamination.
