    Applications

    Polymerization of styrene:TBPB can be used for the polymerization and copolymerization of styrene in the temperature range of 100-140℃. During polymerization the temperature is increased in steps.
    Polymerization of acrylates and methacrylates:TBPB can be used as initiator for the solution (co)polymerization of acrylates and methcrylates in the temperatures range of 100-170℃, amongst others for the coatings.
    TBPB can also be applied as an initiator for the bulk and suspension (co)polymerization of acrylates and methcrylates.
    Polymerization of ethylene:TBPB is an efficient initirtor for the ethylene polymerization under high pressure in both autoclave and tubular processes.To obtain a wide spectrum of polymerization temperatures, combinations with other peroxides are applied in practice.
    Depending on reaction conditions. TBPB is active in the temperature range of 220-270℃.
    Other applications:TBPB can also be used for the (co)polymerization of acrylonitrile and vinyl acetate.
    Crosslinking Peroxides:TBPB,is suitable for crosslinking of EPDM rubber compounds at ambient temperature within some weeks.
    Rubber compounds containing TBPB have moderate processing safety in combination with a very high speed of cure.
    Peroxides for Thermoset Resins:Tert-butyl peroxybenzoate is an aromatic perester which is used for the curing of unsaturated polyester resins at elevated temperatures.TBPB is preferred for the curing of UP resin based Hot Press Moulding formulations (SMC, BMC, ZMC etc) in the temperature range of 120 - 170℃.
