• Organic Peroxide Application Guide

    Comprehensive reference for selecting and using organic peroxides in polymerization, crosslinking, and curing applications. Ensure optimal performance and safety in your chemical processes.

  • Primary Applications of Organic Peroxides

    Organic peroxides serve as essential initiators and crosslinking agents in various industrial processes

    Polymerization Initiator

    Organic peroxides decompose to generate free radicals that initiate chain-growth polymerization of vinyl monomers.

    Common Uses:

    • Low-density polyethylene (LDPE) production
    • Polyvinyl chloride (PVC) manufacturing
    • Polystyrene and acrylic resin synthesis
    • Styrene-butadiene rubber (SBR) production

    Key Peroxides: Di-tert-butyl peroxide, Benzoyl peroxide, Lauroyl peroxide

    Polymer Crosslinking

    Used to create covalent bonds between polymer chains, improving thermal and mechanical properties.

    Common Uses:

    • Cross-linked polyethylene (XLPE) for cables
    • Ethylene-propylene-diene monomer (EPDM) rubber
    • Silicone rubber vulcanization
    • Polymer modification for enhanced properties

    Key Peroxides: Dicumyl peroxide, 2,5-Dimethyl-2,5-di(tert-butylperoxy)hexane

    Resin Curing & Hardening

    Initiate the curing process of unsaturated polyester resins and other thermosetting polymers.

    Common Uses:

    • Fiber-reinforced plastics (FRP) production
    • Gel coats and surface coatings
    • Composite materials manufacturing
    • Automotive parts and marine applications

    Key Peroxides: Methyl ethyl ketone peroxide (MEKP), Cumene hydroperoxide

  • Organic Peroxide Selection Guide

    Key factors to consider when choosing the right organic peroxide for your application
    Selecting the appropriate organic peroxide requires careful consideration of multiple factors to ensure optimal performance, safety, and cost-effectiveness.

    Decomposition Temperature

    Match the peroxide's 10-hour half-life temperature to your process temperature requirements.

    Application Type

    Consider whether you need polymerization, crosslinking, or curing functionality.

    Safety Considerations

    Evaluate thermal stability, sensitivity to contamination, and storage requirements.

    Regulatory Compliance

    Ensure the selected peroxide meets industry and regional regulatory standards.

  • Safety & Handling Guidelines

    Critical safety information for working with organic peroxides

    Thermal Stability

    Organic peroxides are thermally unstable. Always store at recommended temperatures and avoid exposure to heat sources. Know the self-accelerating decomposition temperature (SADT) for each peroxide.

    Contamination Risks

    Avoid contact with promoters, accelerators, heavy metals, strong acids, or bases which can cause rapid decomposition. Use dedicated equipment for each peroxide type.

    Resin Curing & Hardening

    Store in original containers away from direct sunlight. Maintain proper inventory rotation (FIFO). Keep storage areas well-ventilated and equipped with appropriate fire protection.

    Personal Protection

    Always wear appropriate PPE including chemical-resistant gloves, safety goggles, and protective clothing. Have emergency eyewash stations and safety showers accessible.
