Purpose

It is mainly used as catalyst, bleaching powder and deodorant, crosslinking agent of unsaturated polyester, initiator for polymerization, and rubber vulcanizing agent.

Emulsion polymerization, sulfur addition to natural raw rubber, improvement of cetane number of diesel fuel, introduction of tert butyl peroxide group, also used as crosslinking agent for unsaturated polyester at moderate and high temperatures. Used as initiator of anaerobic adhesive and fast curing acrylate structural adhesive. It is also used as an initiator for polymerization reaction (elimination after monomer polymerization in acrylic lotion).

Storage and Transportation

The warehouse is ventilated at low temperature; Light loading and unloading; Store separately from organics, reducing agents, sulfur and phosphorus combustibles.
