Tert-Butyl Perbenzoate (TBPB)

Uses

Initiator for polymerization or copolymerization of ethylene, styrene, acrylonitrile, vinyl acetate, acrylate, methacrylate.

Used as medium temperature initiator, curing agent for unsaturated polyester resin, and vulcanizer for silicone rubber.

Polymerization of acrylate and methacrylate In the temperature range of 100-170℃, TBPB can be used as an initiator for solution polymerization and copolymerization of acrylate and methacrylate, especially for the production of coatings.
