。Application
1. Polymerization of styrene
LQ-TBPEH can be used for the polymerization of styrene in the temperature range of 90℃. During polymerization the temperature is increased in steps.LQ-TBPEH has an activity comparable with LQ-BPO.
2. Polymerization of ethylene
LQ-TBPEH is an efficient initirtor for the ethylene polymerization under high pressure in both autoclave and tubular processes.
3.Peroxides for Thermoset Resins
LQ-TBPEH is an aromatic perester, which is used for the curing of unsaturated polyester resins at elevated temperatures.
LQ-TBPEH is preferred for the curing of UP resin based Hot Press Moulding formulations (SMC, BMC, ZMC etc) in the temperature range of 120 - 170℃.
