An organic peroxide is any organic molecule containing a ‘peroxy’ or oxygen-oxygen bond (-O-O-). Organic peroxides (hereinafter OP) are highly explosive and major accidents are not rare in the industry. They are available as solids (usually fine powders), liquids or pastes. OP and mixtures containing OP are used as accelerators, activators, catalysts, cross-linking agents, curing agents, hardeners, initiators and promoters. OP can be distinguished both by their three main ‘applications’ and by the seven ‘classes’.
