Uses:

1. Excellent low-temperature initiator for high-pressure polyethylene (LDPE), mostly used in tubular process, can be combined with initiator TBPV (tert-butyl peroxypivalate), TBPEH (tert-butyl peroxy-2-ethylhexanoate), TBPEH (tert-butyl peroxy-2-ethylhexanoate), TBPEH (tert-butyl peroxy-2-ethylhexanoate).

(butyl ester), initiator TBPB (tert.Butylperoxybenzoate) composite initiator system, the polymerization effect is better.

2. is a high temperature curing agent for unsaturated polyester.

3. It can be used as an initiator for the polymerization of styrene or copolymers of styrene and as an initiator for the polymerization of methacrylates and vinyl acetate.
