PDM-75/40

Characteristics and Applications

A sulfur-free crosslinking agent with good dispersibility. It functions as a vulcanizing agent and auxiliary vulcanizer for various synthetic rubbers and rubber-plastic blends, and can serve as a co-vulcanizing agent for peroxides. It can replace all sulfur-containing vulcanizers such as thiazoles and thiurams, resolving the problem of black discoloration and contamination of copper wires and copper electrical components caused by copper sulfide formed upon contact with sulfur-containing vulcanizing agents. It improves scorch safety, vulcanization crosslink density and heat resistance, reduces the compression set of rubber compounds, and enhances the bonding strength between rubber and metals as well as cords. When compounded with sulfur in natural rubber, it inhibits vulcanization reversion, boosts heat resistance and lowers heat build-up of the compound. It is suitable for specialty large tires, large-size rubber products, rubber cables and other rubber goods.
