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 & Methacrylates
Used as an initiator for the solution (co)polymerization of acrylates and methacrylates in the temperature range of 100-170℃, amongst others for coatings. It can also be applied as an initiator for bulk and suspension (co)polymerization.
Polymerization of Ethylene
An efficient initiator for ethylene polymerization under high pressure in both autoclave and tubular processes. Active in the temperature range of 220-270℃, combinations with other peroxides are applied in practice to obtain a wide spectrum of polymerization temperatures.
Other Polymerization Applications
TBPB can also be used for the (co)polymerization of acrylonitrile and vinyl acetate.
Crosslinking Peroxides
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 used for the curing of unsaturated polyester (UP) resins at elevated temperatures. It is preferred for the curing of UP resin-based Hot Press Moulding formulations (SMC, BMC, ZMC etc) in the temperature range of 120-170℃.
