Luperox® organic peroxide formulations with Scorch Protection offer flexibility to mix, extrude, and mold rubber compounds at high temperatures while reducing loss due to scorch (premature crosslinking).

Luperox^® diacyls are widely used as curing agents for unsaturated polyester resins used in molded composites, and for skin care to treat acne.  At larger scales, diacyls are useful in bulk polymerization of styrene to form expandable polystyrene.

Luperox^®, Vul-Cup^®, and Di-Cup^® dialkyl peroxides are initiators for high polymers and efficient crosslinking and viscosity modifiers for polyolefins, or vulcanizing agents for elastomers.  Arkema offers a variety of pure and inert-diluted grades, or specialty grades with scorch-protection.
 

Luperox^® tertiary-butyl and tertiary-amyl hydroperoxides are widely used as chemical intermediates and as free radical polymerization initiators.

Luperox^® methyl ethyl ketone peroxides are used for curing unsaturated polyester resins or vinyl ester resins at ambient temperatures in combination with amine or heavy metal promoters.

Luperox^® peroxydicarbonate initiators are widely used for the polymerization of vinyl chloride, or in combination with Luperox^® peroxyesters to polymerize ethylene or acrylic polymers.
