Description of key information

Tert-amyl peroxy-2-ethylhexanoate is a liquid organic peroxide, Type D (determined by UN test method), with a SADT (Self-Accelerating Decomposition Temperature) of 35°C.

The substance has a low melting range (determined -75°C till -1.1°C); the boiling point (extrapolated value is 169°C) and the flash point (58.5°C) are greater than SADT (the substance will decompose before boiling or reaching the flash point).

The relative density at 20°C is 0.8963, and log Kow = 4.56 at 25°C . The vapor pressure is less than 0.01Pa (the substance is considered to be not volatile).

The viscosity is 4.64 mPa.sec @ 30 rpm, 20 oC.
