  • Applications

    Perodox® 133-CK60 can be applied in the solution and non-aqueous dispersion polymerization and methacrylates for the manufacture of coatings. In solution polymerization, Perodox® 133-CK60 is typically applied in combination with another initiator such as dibenzoyl peroxide (Perodox® L75), tert-Butyl peroxy-2-ethylhexanoate (Perodox® 21), or Di-tert-butyl peroxide (Perodox® B).

    LDPE Polymerization

    TAPA serves as an effective low-temperature initiator for high-pressure polyethylene (LDPE) polymerization, primarily used in tubular processes. It can be combined with other initiators like tert-butyl peroxyvalerate, tert-butyl peroxy-2-ethylhexanoate, and tert-butyl peroxybenzoate to enhance polymerization efficiency.

    Unsaturated Polyester Resins

    This peroxide acts as a high-temperature curing agent for unsaturated polyester resins, making it ideal for applications that require robust thermal properties. It facilitates cross-linking reactions that improve the mechanical strength and heat resistance of composite materials.

    Specialty Polymers

    Plays a significant role in the production of ethylene-vinyl acetate (EVA) copolymers, contributing to the manufacturing of materials with specific elasticity and durability characteristics.
