TBPEHC is a colorless, flowable liquid composed primarily of technically pure tert-butyl peroxy-(2-ethylhexyl) carbonate. This thermally stable carbonate monoperoxide is used as an initiator (source of free radicals) in monomer (SM) polymerization, unsaturated polyester (UP) curing and polymer (EVA) crosslinking. Technical Data Appearance: colorless liquid Peroxide content: approx. 991 TP6T w/w Reactive oxygen content: approx. 6.431 TP6T w/w No inhibitors Density (20°C): approx. 0.93 g/cm³ Viscosity (20°C): approx. 6 mPa-s Refractive index (20°C): approx. 1.428 Critical

NOROX ® 400 is a colorless, flowable liquid composed primarily of technically pure tert-butyl peroxy-(2-ethylhexyl) carbonate. It is a carbonate monoperoxide with advantages in thermal stability and is used as an initiator (source of free radicals) in curing agents for unsaturated polyester resins. Main areas of application include hot compression molding of SMC or BMC at 130-160°C. Technical Data Appearance: colorless liquid Peroxide content: approx. 99% w/w Reactive oxygen content: approx. 6.43% w/w No inhibitors Density (20°C): approx. 0.93 g/cm³ Viscosity (20°C): approx. 6 mPa
