hot sales Influence of TMTM as the Secondary Accelerator for natural rubber
Primary And Secondary Accelerator - China Rubber Accelerator
A secondary accelerator usually causes the compound to be scorched and has an ultra-fast vulcanization rate. Promoter combination purpose: to improve the effect of the accelerator and for the needs of the process, such as avoiding scorch, preventing frosting, improving vulcanization flatness.

Vulcanization - an overview | ScienceDirect Topics
Vulcanization. Vulcanization is a chemical process in which the rubber is heated with sulphur, accelerator and activator at 140–160°C. The process involves the formation of cross-links between long rubber molecules so as to achieve improved elasticity, resilience, tensile strength, viscosity, hardness and weather resistance.
