Half life data

The most important characteristic of a cross-linking peroxide is its decomposition rate expressed by its half life (t)

at various temperatures. For BPIB in a EPDM compound:

　 t 　　　 0.1 hr 　　　　 1 hr 　　　　 10 hr
　 at 　　　 169℃ 　　　 146℃ 　　 117℃
　 For BPIB Ts max. = 30℃

Major decomposition products

Methane, Acetone, tert-Butanol, Di(2-hydroxyisopropyl)benzene, Diacetylbenzene, Acetyl 2-hydroxyisopropyl benzene.

Packaging and transport
