Perodox® 122 - 1,1-Di(tert-amylperoxy) cyclohexane

The optimal temperature range for polyethylene crosslinking applications is between 90-120°C, where the compound provides controlled decomposition kinetics that ensure thorough crosslinking without premature degradation. This temperature alignment maximizes crosslinking efficiency while maintaining polymer integrity.

The tert-amylperoxy groups attached to the cyclohexane ring provide thermal stability while allowing controlled radical generation at specific temperatures. The cyclohexane backbone contributes to the compound's compatibility with various polymer matrices.

Critical safety measures include storage at temperatures not exceeding 25°C, separation from incompatible materials, and using explosion-proof equipment in storage facilities. Personal protection during handling operations is mandatory, including appropriate PPE and engineering controls.
