Luperox® 101PP20, 101PP10 and 101PP7.5 viscosity modifiers are 20%, 10% or 7.5% active weight dispersions of Luperox® 101 polymer initiator on polypropylene powder carriers. Luperox® 101PP20, 101PP10 and 101PP7.5 can be easily mixed in twin- or single-screw kneading for blending or single-streaming polyolefins and recycled materials.

DiCup® R/Luperox® DCP Diisopropyl peroxide is used as a high temperature crosslinker in rubber and plastic applications. Compounds containing DiCup® R/ Luperox® DCP are processed at temperatures up to 250°F (121°C) and can cure at temperatures above 300°F (149°C). DiCup® R/Luperox® DCP is also used in the polymerization of EPS, as a finishing agent and as a synergist in flame retardant EPS applications.

Luperox® 546M75 polymer initiator is a highly reactive peroxide ester initiator typically used for the polymerization of vinyl chloride in emulsion synthesis. The free radicals generated are very efficient, resulting in improved monomer conversion compared to systems using tert-butyl peroxide (e.g. Luperox® 10).

Luperox® 7M50 polymer initiator can be used for the polymerization of ethylene in tubular or autoclave reactors or for the emulsion polymerization of acrylic resins. For the production of polystyrene, Luperox® 7M50 can also be used to improve grafting efficiency and molecular weight distribution.
