Applications
- 1. An excellent low-temperature initiator for high-density polyethylene (LDPE), commonly used in the tubular process. It can be combined with initiators such...
- butyl ester), and initiator TBPB (tert-butyl perbenzoate) to form a composite initiator system, which yields better polymerization results.
- 2. A high-temperature curing agent for unsaturated polyesters.
- 3. Can be used as a polymerization initiator for vinyl chloride, styrene, or styrene copolymers, as well as for methacrylates and vinyl acetate.
