Question 1

What is the 10-hour half-life temperature of CH (CAS 3006-86-8)?

Accepted Answer

The 10-hour half-life temperature of 1,1-Bis(tert-butylperoxy)cyclohexane (CH, CAS 3006-86-8) is 91°C. The 1-hour half-life is approximately 111°C. This medium-to-high temperature range makes CH an excellent initiator for bulk and suspension polymerization of styrene (PS, EPS) and crosslinking of polyolefins at processing temperatures of 120–160°C.

Question 2

What are the main applications of 1,1-Bis(tert-butylperoxy)cyclohexane (CAS 3006-86-8)?

Accepted Answer

CH (CAS 3006-86-8) is widely used as: (1) A polymerization initiator for EPS (expandable polystyrene) and PS production; (2) A crosslinking agent for polyethylene and EVA compounds; (3) An initiator for acrylic and MMA polymerization; (4) A curing agent for unsaturated polyester resins. Its bifunctional peroxide structure provides efficient decomposition over a broad temperature range.

Question 3

Where can I source CH (1,1-Bis(tert-butylperoxy)cyclohexane, CAS 3006-86-8) from China?

Accepted Answer

LAAP supplies CH (CAS 3006-86-8) directly from our manufacturing facility in Lanzhou, China. As China's first organic peroxide manufacturer since 1966, we offer competitive factory pricing, REACH documentation, and reliable cold-chain export to Russia, Europe, and Central Asia.

Question 4

What is the difference between CH (CAS 3006-86-8) and CH335 (CAS 6731-36-8)?

Accepted Answer

CH (1,1-Bis(tert-butylperoxy)cyclohexane, CAS 3006-86-8) and CH335 (1,1-Bis(tert-butylperoxy)-3,3,5-trimethylcyclohexane, CAS 6731-36-8) are both bifunctional ketone peroxides. CH335 has a higher 10-hour half-life temperature (90°C vs 91°C for CH, nearly identical) but different decomposition kinetics due to the trimethyl substituents. CH335 is more commonly used in EPS processes requiring precise temperature control, while CH is preferred for general-purpose crosslinking.
