    3. It is also used as a cross-linking agent for natural rubber, silicone rubber, diene rubbers, polyurethane, and EVA copolymers. Compared to other peroxides, CH335 operates at lower cross-linking temperatures and produces less odor, making it the preferred choice for black resin products in BMC/SMC curing applications.
    1. 1,1-Bis(tert-butylperoxy)cyclohexane (CH)
      Inquiry
    2. 1,1-Bis(tert-butylperoxy)cyclohexane (CH)

      CAS No.: 3006-86-8

      Molecular Formula: C₁₄H₂₈O₄
      Molecular Weight: 260
      UN No.: 3105

    3. CH is used in styrene polymerization processes, operating best at temperatures between 90°C and 120°C. It also acts as a reliable initiator for copolymers like acrylonitrile, acrylates, and methacrylates.
      This organic peroxide is highly effective as a curing agent for unsaturated polyester resins (UP resins) in high-temperature applications. It’s a go-to option for curing in processes like SMC, DMC, and BMC, with optimal temperatures ranging from 120°C to 170°C.
    1. 2,2-Di(tert-butylperoxy)butane (DBPB)
      Inquiry
    2. 2,2-Di(tert-butylperoxy)butane (DBPB)

      CAS No.: 2167-23-9

      Molecular Formula: C₁₂H₂₆O₄
      Molecular Weight: 234.3
      UN No.: 3103
