- Excellent low-temperature initiator for high-pressure polyethylene (LDPE) production, especially suited for tubular reactor processes. When used together with other initiators like LQ-TBPV (tert-butyl peroxyvalerate), LQ-TBPEH (tert-butyl peroxy-2-ethylhexanoate), and LQ-TBPB (tert-butyl peroxybenzoate), it enhances the overall polymerization process, improving efficiency and end-product quality.
- An excellent option for high-temperature curing in unsaturated polyester applications, ensuring efficient crosslinking and reliable end results.
- From styrene to vinyl acetate and methacrylates, TBPA facilitates a wide range of polymerization reactions, ensuring fast processing times and improved polymer properties.
