Applications and Features 

XJ-TBPEH is widely used as an initiator in the polymerization of ethylene and styrene, offering reliable performance in various industrial applications. It is an efficient initiator that can quickly  initiate polymerization at  lower temperatures, increasing  the production capacity of polymerization reactors.It also acts as an effective high-temperature curing agent, particularly for unsaturated polyester resins. 

●  XJ-TBPEH is frequently used as a reliable initiator in both autoclave and tubular processes for ethylene polymerization. It also serves as an initiator for acrylates and methacrylates, functioning within a temperature range of 80-150°C.

●  XJ-TBPEH demonstrates higher activity than benzoyl peroxide (BPO) in styrene polymerization. It is often used in combination with other peroxides, such as TBPB and TBEC, and is particularly effective in initiating copolymers like ethylene-vinyl acetate (EVA).

●  XJ-TBPEH is widely applied as a high-temperature curing agent for unsaturated polyester  resins, with curing temperatures between 120-160°C. It’s the preferred choice for curing processes in compression molding (DMC, BMC). TBPEH can also be used  at lower temperatures (around 60°C) with cobalt-based accelerators in processes like air-drying paints and filament winding.

XJ-TBPEH is equivalent to Nouryon TRIGONOX 21S , LUPEROX 26.
