Description
Cumene hydroperoxide (CAS 80-15-9) is an organic peroxide supplied under trade names including Percumyl H, LUPEROX CU90, and TRIGONOX K-80. It carries no assigned E-code and is identified under EC number 201-254-7 with molecular formula C9H12O2.
In plastics and polymer manufacturing, cumene hydroperoxide functions as a radical polymerization initiator, generating free radicals upon thermal decomposition to drive chain-growth reactions. In rubber and tire production, it serves as a cross-linking agent, forming covalent bonds between polymer chains to improve mechanical strength and heat resistance.
Cumene hydroperoxide is available commercially in concentrations typically ranging from 80 to 90 percent active content. It is subject to REACH registration requirements within the European Union and classified under HS code 29096000 for customs purposes. Packaging formats follow ADR transport regulations applicable to organic peroxides.
