Thermal Stability Info
SADT
5°C (41°F)
Emergency Temp (Tₑ)
-5°C (23°F)
Control Temp (Tc)
-15°C (5°F)
Organic peroxides are thermally unstable substances, which may undergo self-accelerating decomposition. The lowest temperature at which self-accelerating decomposition of a substance in the original packaging may occur is the Self Accelerating Decomposition Temperature (SADT). The SADT is determined on the basis of the Heat Accumulation Storage Test (recognized by United Nations, New York and Geneva).
Applications
EHP is an efficient initiator for the production of Low Density Polyethylene (LDPE). It is used both for tubular and autoclave processes. In most cases a combination with other peroxides is used to ensure a broad reactivity range. EHP is applied as an initiator for the suspension and mass polymerization of vinyl chloride in the temperature range between 40°C and 65°C.
