United Initiators TBPEHC tert.Butylperoxy-2-ethylhexylcarbonate 34443-12-4

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 (free radical source) in monomer (SM) polymerization, unsaturated polyester (UP) curing, and polymer (EVA) crosslinking.

Technical data

  • Appearance: colorless liquid
  • Peroxide content: approx. 99% w/w
  • Active oxygen content: approx. 6.43% 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 temperature (SADT): approx. 70°C
  • Refrigeration stability: below -30°C
  • Recommended storage temperature: 20°C maximum
  • Storage stability (from date of delivery): 3 months

appliance

  • Initiator for systemic Morrigan polymerization, e.g., polymerization of styrene (SM).
  • Often used with benzoyl peroxide (BPO) in suspension or tert-butyl peroxy-2-ethylhexanoate (TBPEH) in block polymerization.
  • Temperature range: 100°C - 140°C.
  • Usage: 0.021 TP3T - 0.11 TP3T as supplied.
  • Advantages: Reduced residual monomer content in the polymer, no aromatic decomposition products.

wrap

  • 25 kg HDPE drums.
