。Application

1. Polymerization of styrene
　LQ-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.

2. Polymerization of acrylates and methacrylates
　LQ-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.
　LQ-TBPB can also be applied as an initiator for the bulk and suspension (co)polymerization of 　
　acrylates and methcrylates.

3. Polymerization of ethylene
　LQ-TBPB 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-TBPB is active in the temperature range of 220-270℃.

4. Other applications
　LQ-TBPB can also be used for the (co)polymerization of acrylonitrile and vinyl acetate.

5. Crosslinking Peroxides
　LQ-TBPB,is suitable for crosslinking of EPDM rubber compounds at ambient temperature within 
　some weeks.
　Rubber compounds containing LQ-TBPB have moderate processing safety in combination with a 
　very high speed of cure.

6. Peroxides for Thermoset Resins
　LQ-TBPB, tert-butyl peroxybenzoate, is an aromatic perester, which is used for the curing of 
　unsaturated polyester resins at elevated temperatures.
　LQ-TBPB is preferred for the curing of UP resin based Hot Press
　Moulding formulations (SMC, BMC, ZMC etc) in the temperature range of 120 - 170℃.
