Usage

Application	Details
Polymerization Initiator for Vinyl and Diene Monomers	Crosslinking temperature range: 180-240°C. Common initiator for high-pressure polyethylene (HDPE, LDPE) polymerization. Crosslinking temperature range: 240-280°C.
Curing Agent for Unsaturated Polyester	Used as a curing agent for high-temperature curing of unsaturated polyesters.
Curing Agent for Diene-based Rubbers	Suitable for vulcanizing thick rubber products. Provides excellent tensile strength, elongation, compression resistance, and permanent deformation performance. Approved by the FDA. Can be used for vulcanizing various rubbers, polyurethane elastomers, and silicone rubbers.
Polypropylene High-Speed Spinning	Used as a molecular weight modifier in polypropylene (PP) high-speed spinning (polypropylene fibers). Improves melt index, narrow molecular weight distribution, and uniform fiber formation. Enhances flowability for fast molding processes, while minimizing deformation. Modified PP can be used in films.
Additive for Oils and Transformer Oil	Used as a pour point depressant in oils and transformer oils.
