What role does a vulcanizing agent play in rubber?


Release date:

2018-10-22

A compounding agent that enables rubber molecular chains to crosslink, forming vulcanized rubber. The vulcanizing agent facilitates a crosslinking reaction among the rubber molecules, transforming linear chains into a robust, three-dimensional network structure. This process reduces plasticity while significantly enhancing elasticity and strength. Except for certain thermoplastic rubbers that don’t require vulcanization, both natural rubber and various synthetic rubbers must be formulated with a vulcanizing agent to undergo the curing process. It’s only after vulcanization that rubber acquires its invaluable practical properties, with mechanical performance dramatically improved.
