Antiozone agent for chloroprene rubber, chloro-sulfonated polyethylene rubber, chloro-ether rubber, styrene butadiene rubber, nitrile rubber. In the neoprene rubber can improve the heat resistance of the rubber, reduce the discoloration of the rubber in the sun, a little slow effect on vulcanization. It is also a heat stabilizer in chloro-sulfonated polyethylene compound vulcanized by metal oxides. In styrene butadiene rubber, this product has good protection against ozone and weather aging cracking and flexion cracking, but has no antioxidant effect, so it needs to be used with excellent antioxidants. This product is easy to disperse in the rubber material, can make the rubber material green, but not pollution. In the general amount of chloroprene rubber is 1-2, styrene butadiene rubber is 0.5-3.
