APPLICATION:
ETU-80 can accelerate vulcanization rate of CR and has high scorching safety. It is an activator and secondary accelerator for low-sulfur or non-sulfur vulcanization of other dienes rubber. It can improves heat-proof aging and physical mechanics properties of vulcanizates. Generally it causes no blooming appearance.
