| TBPEH Product description Tert-Butyl peroxy-2-ethylhexanoate Active Oxygen content : 7.0% CAS No. : 3006-82-4 Specification Appearance : clear liquid Color : 20 Pt-Co max. Assay : 97% min. Hydroperoxides as TBHP : 0.1% max. Inorganic + organic hydrolysable chloride : 100 mg/kg max. Physical properties Density, 20℃ : 895 kg/m3 Viscosity, 20℃ : 4 mPa.s Major decomposition products Carbon dioxide, 2-ethyl hexanoic acid, tert-butanol, acetone, methane, ethane, n-heptane, 5,6-diethyldecane. Packaging Standard packaging size for TBPEH is 20 kg net. Smaller packaging size is available on request. Application 1. Polymerization of styrene TBPEH can be used for the polymerization of styrene in the temperature range of 90℃. During polymerization the temperature is increased in steps, TBPEH has an activity comparable with BPO. 2. Polymerization of ethylene TBPEH is an efficient initirtor for the ethylene polymerization under high pressure in both autoclave and tubular processes. 3.Peroxides for Thermoset Resins TBPEH is an aromatic perester, which is used for the curing of unsaturated polyester resins at elevated temperatures. 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℃.
