Purpose:

1. High pressure polyethylene (LDPE) is an excellent low-temperature initiator, commonly used in tubular processes. It can be used in a composite initiator system with initiators TBPV (tert butyl peroxyvalerate), TBPEH (tert butyl peroxy-2-ethylhexoate), and TBPB (tert butyl peroxybenzoate), resulting in better polymerization effects.

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

3. It can be used as a copolymer polymerization initiator for styrene or styrene, as well as a polymerization initiator for methacrylate and vinyl acetate.

Packaging and transportation:

The standard packaging is 20 kilograms of polyethylene drum packaging. We can also supply according to the packaging size requested by the customer, and the customer can make requirements when placing an order.

Storage precautions:

1. Store in a cool and ventilated space, with a warehouse temperature not exceeding 30 ℃.
