Purpose:

1. Polymer crosslinking agent: It is an organic peroxide crosslinking agent that can be widely used in various polymers, especially for polyethylene (LDPE, HDPE) and ethylene/vinyl acetate copolymer (EVA). The crosslinking temperature is above 1850C, and the dosage is 0.5% -3.8% (W/W).

2. It is an excellent degradation agent for polypropylene: it can be made into rheological polypropylene with low molecular weight and narrow molecular weight distribution, and high melt index. It can be used as an important initiator for high-speed spinning materials, coating materials, film materials, and casting plastics.

3. It is an initiator for styrene polymerization and copolymerization. The polymerization temperature exceeds 30-185 ° C.

Packaging and transportation:

The standard packaging is 20 kilograms of polyethylene packaging, which can also be supplied according to the packaging size requested by the customer. 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 30° C.

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