As a multifunctional rubber additive, HVA-2 can be used as a vulcanizing agent in the rubber processing process, as a vulcanizing agent for peroxide systems, and as a scorch retardant. It is suitable for general purpose rubber as well as for general purpose rubber. Used in special rubber and rubber and plastic systems.
2, in natural rubber, with sulfur, can prevent vulcanization and reversion, improve heat resistance, reduce heat generation, anti-aging, improve rubber and cord adhesion and vulcanization modulus. It can be used in the rubber of shoulder rubber and buffer layer of load tires to solve the shoulder-space problem of skew truck tires. It can also be used for large-size thick products of natural rubber and various rubber sundries
3, HVA-2 in neoprene, chlorosulfonated polyethylene rubber, styrene butadiene rubber, nitrile rubber, isoprene rubber, butyl rubber, with, bromobutyl rubber, acrylate rubber, silicone rubber As a kind of auxiliary vulcanizing agent, it can significantly improve the correlation performance and improve the heat resistance. It is suitable for high temperature vulcanization system, reducing compression set and deformation, and reducing the amount of peroxide and preventing glue. The scorch during the processing increases the bond strength between the rubber and the cord and the metal.
4, HVA-2 is a sulfur-free vulcanizing agent, used in cable rubber, it can replace all sulfur-containing vulcanizing agents such as thiazoles and thirams, and solves the problem that copper wires and copper appliances are contaminated with copper sulfide due to contact with sulfur-containing vulcanizing agents. Black puzzle.
The volume of Usage:The scorch retarder is 0.5-1.0 part, the vulcanizing agent is 2-3 parts, the compression set is improved to 1.5 parts, and the adhesive strength is 0.5-5.0 parts.
