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. It can also be applied as an initiator for the 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℃.
Crosslinking Peroxides
Suitable for crosslinking of EPDM rubber compounds at ambient temperature within some weeks. Offers moderate processing safety with very high speed of cure.
Thermoset Resins
Preferred for curing UP resin based Hot Press Moulding formulations (SMC, BMC, ZMC etc) in the temperature range of 120 - 170℃.
Other applications
Can also be used for the (co)polymerization of acrylonitrile and vinyl acetate.
