| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| use | HVA-2 is used as a multifunctional rubber additive. it can be used as a vulcanizing agent, a vulcanizing agent for peroxide system, an anti-scorch agent and a tackifier in the rubber processing process. it is suitable for both general-purpose rubber and special rubber and rubber-plastic systems. In natural rubber, combined with sulfur, it can prevent vulcanization from returning to the original, improve heat resistance, reduce heat generation, aging resistance, and improve the adhesion force of rubber and cord and the modulus of vulcanized rubber. Used in load tire shoulder rubber, buffer layer and other rubber, it can solve the problem of skew load tire shoulder empty, and can also be used for large-size thick products of natural rubber and various rubber miscellaneous products. HVA-2 in neoprene, chlorosulfonated polyethylene rubber, styrene butadiene rubber, nitrile rubber, isoprene rubber, butyl rubber, brominated butyl rubber, acrylate rubber, silicon PDM As a multifunctional rubber additive, it can be used as a vulcanizing agent in the rubber processing process, it can also be used as a vulcanizing agent for peroxide systems, as well as a scorching agent and tackifier.
