Application
● Used as a polymerization initiator for ethylene, styrene and styrene copolymers, acrylonitrile, acrylates, and methacrylates.
● Also employed for crosslinking natural rubber, silicone rubber, diene rubber, polyurethane, and ethylene-vinyl acetate (EVA) copolymer resins. Offers lower crosslinking temperatures and reduced odor compared to other peroxides.
Package and Storage
● 20 kg polyethylene drums,Custom packaging sizes available upon request.
● store in a sealed container, in a well-ventilated space, with a maximum storage temperature of 25°C. It’s important to avoid contact with reactive materials like acids, bases, and heavy metal compounds. Ensure the product is protected from friction and impact, and avoid repackaging within the storage facility.
