- TBPV is a highly efficient initiator for the polymerization of ethylene, used in high-pressure tubular and stirred reactor processes.
- It functions as an effective initiator in the suspension polymerization of vinyl chloride (PVC), particularly at temperatures between 50-70°C.
- Also used as an initiator in the suspension polymerization of acrylates and methacrylates, as well as in non-aqueous dispersions for coating production.
- Additionally, TBPV is an important initiator for EVA (ethylene-vinyl acetate) polymerization.
- It acts as a curing agent for unsaturated polyester resins at medium temperatures, typically between 80-100°C, making it suitable for hot press molding processes.
- When added to oils, TBPV significantly enhances their quality.
