Applications
This product is a thiazole ring compound, containing active sulfur atoms, containing halogen polymer cross-linked. It is suitable for crosslinking chlorinated butyl rubber, vulcanized butyl rubber and chlorine, especially as an effective promoter of chloroprene rubber. Compared with na-22, this product maintains good physical performance. Na-22 vulcanized neoprene rubber also has anti-aging performance, improved coking performance and operation safety, and has the characteristics of fast curing. The product is easy to disperse in rubber, no pollution, no color difference, often used in cable, tape manufacturing.
