PDMTD CAS 79509-46-9 Poly(1,3,4-thiadiazole-2,5-diyldithio)

Characteristic

White or light yellow crystal

Application:

This product can be used as vulcanizing agent and accelerator for natural rubber and synthetic rubber. This product will not cause frosting, pollution, discoloration and easy dispersion of the rubber material. The vulcanized rubber obtained when used in effective and semi-effective vulcanization systems has good heat resistance and aging resistance. It can release active sulfur at the vulcanization temperature. The effective sulfur content is 27%. It is safe to operate. When used alone, the vulcanization speed is slow. When used together with thiazoles, thiurams and dithiocarbamate salts, the vulcanization speed can be increased. This product is especially suitable for butyl rubber, which is mainly used in the manufacture of tires, butyl inner tubes, tapes and heat-resistant rubber products. It is also used as asphalt stabilizer on highways.
