Application: Fast-curing primary or secondary accelerator for NR, SBR, Nitrile and EPDM. Closely resembles Willing TMTD in its applications. less scorch, blooming and good processing safety. Can be used in CR as an anti-scorching agent. The efficiency sulphur content is 11 %. It is also be used as raw material for germicide, pesticide and medicine.

Packaging: 25kg plastic woven bag, paper with plastic film bag, 25kg drum.

Storage: The product should be stored in the dry and cooling place with good ventilation, avoiding exposure of the packaged product to direct sunlight. The validity is 1 year.

Notes The product could be ultrafine powder based on customer accurate requirement.

Properties

The backshovel vulcanization accelerator of rubber can also be used as vulcanizing agent. When used as accelerator, its performance in natural rubber is similar to that of accelerator CZ, but the delay is slightly larger. When used in 54-1 (W) chloroprene rubber, combined with accelerator PZ, it can accelerate the vulcanization speed, have good scorch performance and excellent physical properties.
