It is an anti-reversion agent which provides long term heat stability in sulfur vulcanized polymers like NR,IR,SBR,BR etc., It can improve degree of cross-linkage which are degraded by losing of sulfur crosslinks during processing or its service life, by generating carbon-carbon bonds(cross linkage).

Non-reactive at the first state of vulcanization. No need to modify process or recipes.

Effective to fight against thermal degradation.

Melting point range below 90 degree Celsius,easy to disperse.

It can allow a higher processing or curing temperature without giving up performances.
