Luperox® 231XL40 crosslinked peroxide is a 40% active dispersion of Luperox® 231 polymeric initiator on calcium carbonate. This inert desensitizing material significantly reduces safety hazards. Luperox® 231XL40 crosslinking peroxide is particularly suitable for fast curing of engineered rubber products and elastomers using various mixing techniques.

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® 531 polymer initiator can be used for the polymerization of styrenics, acrylics or PMMA and their copolymers. This peroxide can be shipped at ambient temperature, providing customers with greater flexibility than temperature controlled peroxide esters. A wide range of active concentrations are available globally, from 60% to 80%, with the remainder being organic solvents.

Luperox® 223V75 polymer initiator is part of the V-series and significantly improves the shelf life and SADT of Luperox® 223 molecule (commonly known as EHP). volatile organic compounds (VOC) emissions from the polymerization of common PVC have been further improved.

Luperox® 223EN60H emulsion initiator is an aqueous initiator system of bis (2-ethylhexyl) peroxydicarbonate designed to improve ease of use for PVC resin manufacturers. The emulsion system uses water as a heat sink to improve storage and handling safety. Users will also find better PVC resin quality because emulsions are more easily dispersed in suspension media.

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® 188M75 polymeric initiator is an organic peroxide used to increase the throughput of emulsion PVC reactors. In combination with other initiators such as Luperox® 223S or 223M75S polymeric initiators, the use of Luperox® 188M75 polymeric initiator will increase the productivity per hour of reactor time.

Luperox® 101XL45 crosslinking peroxide is a 45% reactive dispersion of Luperox® 101 polymeric initiator on calcium carbonate filler. Luperox® 101XL45 can be used to cure silicone, fluoroelastomer and engineered rubber compounds at standard conditions above 170°C. It can be used to cure silicone, fluoroelastomer and engineered rubber compounds at standard conditions above 170°C.
