Usage
Application | Details |
---|---|
Polyethylene Polymerization (LDPE) | Excellent medium-temperature initiator for high-pressure polyethylene polymerization. Often used in tubular or autoclave methods. Can be combined with other initiators for improved polymerization effects. |
Styrene Suspension Polymerization | Common initiator for styrene and its copolymers when combined with BPO (Benzoyl Peroxide). |
Acrylate Polymerization | Used to replace azo-based initiators, reducing toxicity in the resin. Can also be used for vinyl acetate polymerization. |
Curing Unsaturated Polyester Resins | Preferred curing agent for high-temperature curing of unsaturated polyester resins, especially in SMC, BMC, and DMC molding. |
Rubber Vulcanization | Effective vulcanizing agent for most types of rubber (excluding isobutylene rubber). |
Fuel Additive | Increases the cetane number of diesel fuels. |
