Use

1, Used as initiator for the polymerization of vinyl and dienyl monomers, the recommended cross-linking temperature range is 180-240 °C. It can be used as initiator for the polymerization of vinyl and dienyl monomers. It is a commonly used initiator in Suga method and kettle method of high-pressure polyethylene polymerization process.
2, It is a high temperature curing agent for unsaturated polyester.
3, It is a vulcanizing agent for diene rubber, suitable for vulcanization of 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 rubber, polyurethane elastomers, silicone rubber vulcanization, can be obtained in white and a variety of brightly colored rubber products. 
4, Used in polypropylene high-speed spinning (polypropylene) industry, as molecular weight regulator (used in cooling masterbatch production). With narrow molecular weight distribution, high melt index, spinning uniformity, is an excellent degradation agent used in polypropylene modification, adding the product in polypropylene can be made to control the rheology of polypropylene, improve the fluidity of polypropylene, so that rapid molding of polypropylene possible, while reducing the deformation generated by molding. The modified polypropylene can be made into film material.
5, Used in oil additives and transformer oil pouring agent.

Packing and Transportation
