tert-Butylperoxy 2-ethylhexyl carbonate (TBEC)

TBEC (tert-Butylperoxy 2-ethylhexyl carbonate, CAS 34443-12-4) is a peroxyester initiator used for the polymerization of styrene and acrylates in the 100-130°C range, as a crosslinking agent for EVA, EPDM and natural rubber, and for curing unsaturated polyester resins in hot press moulding.

The 10-hour half-life temperature of TBEC (CAS 34443-12-4) is 98°C. The 1-hour half-life is 117°C and the 0.1-hour half-life is 137°C, making TBEC suitable for processes run between 100°C and 130°C.

TBEC should be stored below 20°C in a cool, well-ventilated area away from heat, direct sunlight and incompatible materials such as acids and reducing agents. Its SADT (self-accelerating decomposition temperature) is 60°C and its UN number is 3105.
