。Application 

1.Polymerization of styrene

LQ-TBPMH can be used for the polymerization and copolymerization of styrene in the 

temperature range of 90-140℃.

2. Polymerization of acrylates and methacrylates

LQ-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.

LQ-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

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

4.Peroxides for Thermoset Resins

LQ-TBPMH, is an perester, which is used for the curing of unsaturated polyester resins at elevated temperatures.

LQ-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℃.
