Usage

Application	Details
Polyethylene Polymerization (LDPE)	Excellent low-temperature initiator for high-pressure polyethylene polymerization, especially in tubular methods. Can be combined with LQ-TBPV (Tert-butyl peroxyvalerate), LQ-TBPEH (Tert-butyl peroxy-2-ethylhexanoate), and LQ-TBPB (Tert-butyl peroxybenzoate) for enhanced polymerization.
Curing Unsaturated Polyester Resins	Used as a high-temperature curing agent for unsaturated polyester resins.
Styrene and Vinyl Ester Polymerization	Effective initiator for styrene or styrene copolymer polymerization and for methyl methacrylate and vinyl acetate ester polymerization.

Packaging and Transportation

Item	Details
Standard Packaging	20 kg polyethylene containers. Custom packaging available upon request.

Storage Instructions
