TBzTD-70

Description

TBzTD-70 is an environmentally friendly thiuram accelerator because tetrabenzyl nitrosamine is not carcinogenic. For NR, SBR, EPDM, and NBR vulcanization systems, it can be used as a fast main accelerator or secondary accelerator. It has a safer and longer scorch time than TMTD and can be used as a PVC rubber vulcanization inhibitor.

Function

JXBHgran TBzTD-70 can accelerate the vulcanization of natural rubber and synthetic rubber with high processing safety, and shorten the scorch and curing time. JXBHgran TBzTD-70 can not only be the main accelerator but also a thiazole auxiliary accelerator in the presence of sulfur. It can also be used as a sulfur-free system curing agent. It can improve the heat-aging resistance characteristics of vulcanized rubber without sulfur cross-linking or with a small amount of sulfur cross-linking.
