Applications:

1. An excellent medium-temperature initiator for low-density polyethylene (LDPE), commonly used in tubular or autoclave processes. It can be combined with initiator PV (tert-butyl peroxy pivalate), OT (tert-butyl peroxy-2-ethylhexanoate), initiator TBPD (tert-butyl peroxy neodecanoate), and diisopropylbenzene hydroperoxide to form a composite catalyst system for improved polymerization results.

2. In the suspension polymerization process of styrene, the combined use of Initiator C and benzoyl peroxide (BPO) is the most common initiator system for styrene or styrene copolymers.
3. In the polymerization of acrylates, Initiator C is used to replace azo initiators, reducing the toxicity in the resin. It can also be used in the polymerization of vinyl acetate.
4. It is a high-temperature curing agent for unsaturated polyester resins. This product is widely used in the curing process of unsaturated polyester resins in applications such as fiberglass-reinforced plastics, coatings, and adhesives, including molding processes such as SMC, BMC, and DMC. It is the preferred curing agent for high-temperature curing of unsaturated polyester resins, providing excellent curing results for both compression molding and pultrusion processes. Even better results can be achieved when combined with initiators such as BPO, TBPEH, and CH to form a composite initiator system.

5. It is a good vulcanizing agent for most rubbers (except isobutylene-based rubbers).
6.  Adding it to petroleum products significantly increases their cetane number.
