1, used as vinyl, dienyl monomer polymerization initiator, the recommended crosslinking temperature range is 180-240 ℃. In the sugary method and kettle method of high-pressure polyethylene polymerization process, it is a commonly used initiator, cross-linking temperature range of 240-280 ℃.

2、It is the high temperature curing agent of unsaturated polyester.

3、It is a vulcanizing agent for diene rubber, suitable for vulcanizing thick rubber products. Good tensile strength, elongation and resistance to compression and permanent deformation, approved by FDA, suitable for most of the rubber, polyurethane elastomer, silicone rubber vulcanization, can get white and various bright colors of rubber products.

4, used in polypropylene high-speed spinning (polypropylene) industry, to do molecular weight regulator (used in the production of cooling masterbatch). Has a narrow molecular weight distribution, high melt index, spinning uniform characteristics.

It is an excellent degradation agent used in polypropylene modification. Adding this product to polypropylene can make rheology-controlled polypropylene, improve fluidity, make it possible to mold polypropylene quickly, and reduce the deformation produced by molding. The modified polypropylene can be made into film material.

5、It is used as oil additive and transformer oil coagulant.

Package and transportation:

The standard packaging of our factory is 20kg polyethylene package.

Storage precautions.

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

2. Keep away from fire and heat source. Store separately from acids, reducing agents, flammable materials, combustible materials, reducing agents, etc.

3. The lighting and ventilation facilities of the storage room should be explosion-proof, and the switch should be located outdoors.

4. When handling, it should be placed carefully and gently to prevent damage to the packaging and containers, to prohibit impact and oscillation, and to pay attention to personal protection when dividing and handling.

5. Please read the MSDS carefully when storing, transporting and using this product.

Product expiration date:

In strict accordance with the manufacturer's instructions for storage and transportation. The product quality can be guaranteed within three months.

Fire protection: 1:

1、The product may be violently decomposed due to heat, will be violent fire, a small amount of product fire should be quickly extinguished with foam or dry powder fire extinguisher.

2, large fires should be quickly withdrawn to a safe distance away and water gun park to save, and notify the fire department to deal with.
