Question 1

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

Accepted Answer

The 10-hour half-life temperature of BPDH (2,5-Bis(tert-butylperoxy)-2,5-dimethylhexane, CAS 78-63-7) is 128°C — one of the highest among common crosslinking peroxides, enabling processing at very high temperatures.

Question 2

What applications is BPDH used for?

Accepted Answer

BPDH is widely used for XLPE high-voltage cable crosslinking, silicone rubber vulcanization, EPDM crosslinking for automotive components, and polypropylene controlled degradation (visbreaking).

Question 3

Can BPDH replace DCP in cable crosslinking?

Accepted Answer

Yes, BPDH can replace DCP in applications requiring higher processing temperatures or where the decomposition profile of BPDH (higher half-life temp) is more suitable. BPDH also produces less volatile decomposition products compared to DCP.
