Properties HA-8’s trade name is HVA-2. Yellow or brown powder, It is soluble in dioxane, tetrahydro furan and hot acetone, and insoluble in petroleum ether, chloroform, benzene and water.

Application HA-8 is a multi-function rubber agent. In the rubber process industry, it can be used as either curing agent, coagent for peroxide curing system or anti-scorcher and adhesion promoter. In addition to general-purpose rubber, it can be applied to special purpose rubber and rubber-plastic blends.It can   solve the problem of copper wire blackening due to copper sulfide resulting form the reaction between copper wire and sulfur containing curing agents.

Usage: anti-scorcher, 0.5-1.0 phr; curing agent 2-3 phr; For improving compression set, 1.5-2.0; For improving adhesive strength, 0.5-5.0 phr.

Packing: PE bag lined with PE film.Net weight:10kg/bag or 25kg/drum.
