Uses.

1. Used as initiator for the polymerization of vinyl and dienyl monomers, with a recommended cross-linking temperature range of 180-240 ℃. In the Kan method and kettle method of high-pressure polyethylene polymerization process, it is a commonly used

The temperature range of cross-linking is 240-280 °C. The initiator of the

2. High temperature curing agent for unsaturated polyester.

3、It is a vulcanizing agent for diene rubber, suitable for vulcanizing thick rubber products. Tensile strength, elongation and resistance to compression and permanent deformation performance is good, approved by the FDA, suitable for the vast majority of the rubber

Vulcanization of rubber, polyurethane elastomers, silicone rubber, white and various brightly colored rubber products can be obtained.

4, Used in polypropylene high speed spinning (polypropylene) industry, as molecular weight regulator (used in cooling masterbatch production). It is characterized by narrow molecular weight distribution, high melt index and uniform spinning.

It is an excellent degradation agent used in polypropylene modification. Adding this product to polypropylene makes it possible to make controlled rheology polypropylene, which improves fluidity and makes rapid molding of polypropylene possible, and at the same time reduces the amount of

Deformation from molding. Modified polypropylene can be made into film stock.

5、Used for oil additives and transformer oil condensation reducer.
