Luperox® 223EN60H emulsion initiator is an aqueous initiator system of di-(2-ethylhexyl) peroxidicarbonate designed to offer improved ease of use to makers of PVC resins. The emulsion system uses water to act as a heat sink to improve safety in storage and handling. Users can also find better PVC resin quality as emulsions disperse much easier in suspension mediums.

Luperox® 221 polymer initiator is unique in the organic peroxide industry. In North America, Arkema at Geneseo NY is the only facility in the Western Hemisphere known to produce this initiator. The performance offered by Luperox® 221 polymer initiator is favored by makers of fluoropolymers for its low impurity and also in the manufacture of PVOH for use in a variety of applications.

Luperox® 223M75 polymer initiator is a 75% active solution of EHP with added organic solvent. Luperox® 223M75S polymer initiator is the same solution, but with an added stabilizer that increases the self accelerating decomposition temperature (SADT). The stabilized solution is widely used in emulsion PVC polymerizations. High pressure applications such as tubular production of LDPE use the 223M75 solution without stabilizer.

Luperox® 219M75 polymer initiator can be used as a free radical initiator for both PVC and polyethylene/EVA manufacturing. The high activity offered by Luperox® 219M75 polymer initiator can optimize production of these polymers when combined with other peroxides.

Luperox® 223S polymer initiator is pure EHP with added stabilizer that increases the self-accelerating decomposition temperature (SADT). Pure EHP is preferred for emulsion polymerization of PVC resins in combination with other initiators. The high volatility of pure EHP and the preference for a safer alternative brought Arkema to offer an emulsion technology, Luperox® 223EN60H emulsion initiator.

Luperox® 223V75 polymer initiator is part of the V-series which dramatically improves the shelf life and SADT of the Luperox® 223 molecule, commonly known as EHP. Further improvements have been noted to the volatile organic content (VOC) emissions that result from normal PVC polymerization.

Luperox® 610EN50 emulsion initiator is a very high activity initiator for use in suspension polymerizations of vinyl chloride to form PVC resins. The very short half-life of Luperox® 610EN50 emulsion initiator can improve conversion rates of vinyl chloride monomer to improve reactor efficiency. This efficiency is well demonstrated in resins with K values more than 65.
