Question 1

What is TBCP used for?

Accepted Answer

TBCP (tert-Butyl cumyl peroxide, CAS 3457-61-2) is primarily used as a high-temperature crosslinking agent for XLPE cable insulation, silicone rubber, and EPDM, and as a controlled degradation agent for polypropylene.

Question 2

How does TBCP compare to DCP?

Accepted Answer

TBCP is often preferred over DCP in odor-sensitive applications such as food-contact materials and medical-grade cables, because TBCP decomposition does not produce acetophenone — the main source of DCP's characteristic odor.

Question 3

What is the 10-hour half-life temperature of TBCP?

Accepted Answer

The 10-hour half-life temperature of TBCP is approximately 120°C, making it suitable for high-temperature processing above 150°C.
