。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℃.
