Question 1

What is the half-life temperature and application of CBPO (CAS 133-14-2)?

Accepted Answer

CBPO (Bis(2,4-dichlorobenzoyl)peroxide, CAS 133-14-2) has a 10-hour half-life of approximately 53°C, making it a low-temperature peroxide curing agent. It is widely used for vulcanizing silicone rubber (silicone curing agent) and as an initiator in low-temperature polymerization. Available as 50% paste for safe handling.

Question 2

Is CBPO (CAS 133-14-2) the same as bis(2,4-dichlorobenzoyl)peroxide for silicone rubber?

Accepted Answer

Yes. CBPO (CAS 133-14-2) — also known as bis(2,4-dichlorobenzoyl)peroxide or DCBP — is one of the primary peroxide curing agents for HTV (high-temperature vulcanization) silicone rubber. When used as a silicone curing agent at 110–130°C, it produces minimal residue. LAAP supplies CBPO as 50% paste (UN 3102) suitable for silicone compound vulcanization.
