Purpose:

1. High pressure polyethylene (LDPE) is an excellent low-temperature initiator, commonly used in tubular processes. It can be combined with initiators TBPV (tert butyl peroxyvalerate), TBPEH (tert butyl peroxy-2-ethylhexoate), and TBPB (tert butyl peroxybenzoate) to form a composite initiator system, 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 vinyl chloride, 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 packaging. We can also supply according to the packaging size requested by the customer, and the customer can make a request when placing an order.

Storage precautions:

1. Store in a cool and ventilated space, with a warehouse temperature not exceeding -10 ℃.

2. Keep away from sparks and heat sources. It should be stored separately from acids, combustibles, combustibles, reducing agents, etc.

3. The lighting and ventilation facilities in the storage room are explosion-proof, with switches located outdoors.

4. When handling, care should be taken to prevent damage to packaging and containers, and impact and oscillation are prohibited. Personal protection should be taken during packaging and handling operations.

5. Please carefully read the Safety Technical Manual (MSDS) when storing, transporting, and using this product.

Product validity period：

Under strict storage and transportation conditions according to the manufacturer's instructions, product quality can be guaranteed within three months.

Fire protection：

1. This product may decompose violently due to heating, and may ignite violently. A small amount of small fires should be put out quickly with foam or dry powder extinguishers.

2. The fire should be quickly evacuated to a safe distance and extinguished with a water gun, and the fire department should be notified for handling.
