1,1-Di(tert-butylperoxy)cyclohexane

1,1-Di(tert-butylperoxy)cyclohexane (CAS 3006-86-8), commercially known as Perkadox 16, initiates free-radical reactions that drive polymer crosslinking and addition polymerization.

Where is 1,1-Di(tert-butylperoxy)cyclohexane used?

• Rubber compounding: crosslinks EPDM, silicone, and natural rubber for vulcanizates with improved heat resistance and compression set
• Unsaturated polyester and acrylic resins: high-temperature cure initiator for controlled exotherm and through-cure
• Wire and cable insulation: initiates peroxide crosslinking of polyethylene
• Adhesive and sealant formulators incorporate it into systems that require elevated-temperature activation and durable bond strength under thermal cycling.

Good to know: It belongs to the dialkyl peroxide class and is selected for its mid-range decomposition temperature, which suits a broad range of processing conditions across rubber and plastics manufacturing.

Commercial specifications

• Liquid concentrate, typically 50% active content on an inert carrier
• Technical grade; purity and active oxygen content specified per batch documentation
• Packaging: drums to intermediate bulk containers
