HVA-2 powder (CAS:3006-93-7) is a yellow or brown powder, soluble in dioxane, tetrahydrofuran and hot acetone, but insoluble in petroleum ether, chloroform, benzene and water. HVA-2 powder is always  used in rubber processing as curing agent,crosslinking agent,and vulcanizing agent. Yangchen Tech is specializing in rubber additives for 30 years. Our HVA-2 powder is already supplied to major chemical companies around the world.We will provide free sample for your testing.

Rubber Vulcanizator PDM N,N'-m-phenylene dimaleimide manufactured by Yangchen Tech referred to as HA-8/HVA-2/PDM can be used as crosslinking agent in rubber processing especially used in tire manufacturing processing.It is a yellow or brown powder, soluble in dioxane, tetrahydrofuran and hot acetone, but insoluble in petroleum ether, chloroform, benzene and water.

Crosslinking agent- N,N'-m-phenylene dimaleimide, referred to as HA-8/HVA-2/PDM, is an important fine chemical raw material with a unique bismaleimide structure. This structure gives HA-8 excellent heat resistance, electrical insulation, mechanical strength and chemical stability, so it has broad application prospects in the field of rubber processing.

N,Nˊ-m-phenylene bismaleimide (also called HA-8 PDM or HVA-2) is a multifunctional rubber additive. It can be used as a vulcanizing agent and an auxiliary agent in the peroxide system during rubber processing. HA-8 can also be used as an anti-scorch agent and a tackifier. It is suitable for both general rubber and special rubber and rubber-plastic systems.
