Rubber vulcanizing agent HVA-2 (PDM), CAS No. 3006-93-7, HVA-2 can be used as both a vulcanizing agent and a co vulcanizing agent for peroxide systems during rubber processing, as well as as an anti coking agent and tackifier. Used in the shoulder rubber, buffer layer and other rubbers of load bearing tires, it can solve the problem of shoulder space in diagonal load tires. HVA-2 can also be used as an auxiliary vulcanizing agent to improve the correlation performance and heat resistance. It is suitable for high-temperature vulcanization systems and significantly reduces compression deformation. It can also reduce the amount of peroxide used, prevent scorching of the rubber material during processing, and improve the bonding strength between the rubber material, cord and metal.
1. HVA-2, as a multifunctional rubber additive, can be used as a vulcanizing agent, a co vulcanizing agent for peroxide systems, and an anti coking agent in the rubber processing process. It is suitable for both general rubber and special rubber and rubber plastic blend systems.
2. In natural rubber, when combined with sulfur, it can prevent and control vulcanization reversion, improve heat resistance, reduce heat generation, resist aging, and improve the adhesion between rubber and cord, as well as the modulus of vulcanized rubber. Used in the shoulder rubber, buffer layer and other rubbers of load-bearing tires, it can solve the problem of shoulder space of diagonal load tires, and can also be used for large-sized thick products of natural rubber and various rubber miscellaneous products.
3. HVA-2, as an auxiliary vulcanizing agent in special rubber such as Neoprene, chlorosulfonated polyethylene rubber, Styrene-butadiene, Nitrile rubber, isoprene rubber, Butyl rubber, brominated Butyl rubber, acrylate rubber, silicone rubber and rubber plastic blends, can significantly improve the correlation performance, improve the heat resistance, apply to high-temperature vulcanization systems, significantly reduce the compression set, and also reduce the amount of peroxide, To prevent scorching of the rubber material during processing and improve the bonding strength between the rubber material and the cord and metal.
4. HVA-2 is a sulfur free vulcanizing agent, which is used for cable rubber. It can replace all sulfur containing vulcanizing agents such as thiazole and thiuram, and solve the problem of Copper monosulfide pollution and black hair caused by copper conductors and copper appliances contacting sulfur containing vulcanizing agents.
