1. Polymer crosslinker: It is an organic peroxide crosslinker that can be widely used in a variety of polymers, especially suitable for the polymerization of polyethylene (LDPE, HDPE) and ethylene/vinyl acetate copolymer

\n

For cross-linking agent, the cross-linking temperature is above 1700C, and no cross-linking occurs below 1400C. The dosage is 0.5%-3% (W/W), and the dosage is generally in some materials that are not prone to cross-linking 1%-5%。

\n

2. It is a high-temperature vulcanizing agent for vinyl silicone rubber: at the same time, it is an excellent vulcanizing agent for other types of rubber, and the vulcanized rubber with this product has the outstanding advantages of high tensile strength and high hardness.

\n

3. It is an excellent degrader for polypropylene degradation: the degradation temperature is 200-2200C, and the dosage is 0.01-0.1%. It can be made into rheological polypropylene with low molecular weight and narrow molecular weight distribution with high melt index, which can be made

\n

It is an important initiator for high-speed spinning materials, coating materials, film materials and cast plastics, and is the preferred raw material for the production of cooling masterbatches.

\n

4. High-temperature curing agent for unsaturated polyester.
