Application

1.Polymerization of styrene

TBPMH can be used for the polymerization and copolymerization of styrene in the temperature range of 90-140℃.

2. Polymerization of acrylates and methacrylates

TBPMH can be used as initiator for the solution (co)polymerization of acrylates and methcrylates in the temperatures range of 90-175℃, amongst others for the coatings.

TBPMH can also be applied as an initiator for the bulk and suspension (co)polymerization of acrylates and methcrylates in the temperature range 90-130℃.

3. Polymerization of ethylene

TBPMH 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. TBPMH is active in the temperature range of 210-270℃.

4.Peroxides for Thermoset Resins

TBPMH, is an perester, which is used for the curing of unsaturated polyester resins at elevated temperatures.
TBPMH is preferred for the curing of UP resin based Hot Press Moulding formulations (SMC, BMC, ZMC etc) in the temperature range of 120 - 170℃.
