Applications
- 1. Used as a polymerization initiator for vinyl and diene monomers; the recommended crosslinking temperature range is 180–240 °C. It is a commonly used
- initiator in tubular and batch-type high-pressure polyethylene polymerization processes, with a crosslinking temperature range of 240–280 °C.
- 2. Serves as a high-temperature curing agent for unsaturated polyesters.
- 3. Acts as a sulfur vulcanizing agent for diene rubbers and is suitable for the vulcanization of thick rubber products. It offers excellent tensile strength,...
- rubber, polyurethane elastomers, and silicone rubber, enabling the production of rubber products in white and a variety of vivid colors.
- 4. Used in the high-speed polypropylene (polypropylene fiber) spinning industry as a molecular weight regulator (used in the production of cooling masterbatc...
