分解溫度 182℃（半衰期 1 分鐘），118—120℃（半衰期 10 小時）。
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. The SADT is 80℃.
