HVA-2(PDM) 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. During NR, combining with sulfur, it can prevent compound form reversion during vulcanization and improve heat resistance, heat build-up, aging resistance and adhesive strength between rubber and cord, as well as modulus of vulcanizate. The shoulder-blowing problem of heavy-duty bias tire can be solved by using HVA-2(PDM) in tire shoulder or buffer stocks. It also can be used in large size and thick rubber articles, and all kinds of miscellaneous fabricated rubber goods.

In special purpose rubber, HVA-2(PDM) can act as secondary curing agent, giving rubber compounds improved cross-link behavior, heat resistance. It is suitable for high temperature curing systems, giving great improved compression set, low amount of peroxide, high adhesive strength between rubber and cord or steel wire and scorch safety during fabricating.
HVA-2(PDM) is sulfur free curing agent and can be used as a substitute for thiurams, thiazoles and other sulfur containing curing agents in cable compounds to solve the problem of copper wire blackening due to copper sulfide resulting form the reaction between copper wire and sulfur containing curing agents.

This product is applicable to top grade hot-dissolvable oil paint, dope to greatly improve the heat resisting property, ligntness, and metal adhesiveness of products. What's more, it also can be used to the adhesive agent to greatly improve its heat resisting property and adhesiveness with the metal. Because this product is fantastic macromolecule heat resisting assistant agent, it also can be used to the heat resistant material of the Space and Aviation.
