- Application
It is a high effective pre-vulcanization inhibitor. It is applied in natural or synthetic rubber, NR, SBR, BR, IIR CR, EPM, EPDM, NBR with cure system consisting of sulfur and Thiazole but mainly Sulphenamide Accelerator.
PVI can effectively prevent the rubber materials from scorching during processing. It makes it possible for extruder and calender to run at high temperature and high speed and improves capacity of the vulcanizer. The poduct can also improve the storage stability of the rubber materials and keep them from natural vulcanization during storage. Meanwhite, it has reclaimaion function for rubber materials that have been borne at high temperature or dangerous for scorching.
