Organic Peroxides / Peroxyesters

Luperox ®

Identification

Luperox® 10 polymer initiator

  • Luperox® 10 polymer initiator is a standard t-butyl peroxyneodecanoate for use in a variety of polymer synthesis applications. The product is available as a pure liquid, 75% dilution in organic solvent, and also as an emulsion in water.

Luperox® 188M75 polymer initiator

  • Luperox® 188M75 polymer initiator is an organic peroxide used to improve throughput in emulsion PVC reactors. In combination with other initiators such as Luperox® 223S or 223M75S polymer initiator, using Luperox® 188M75 polymer initiator will improve productivity per hour of reactor time.

Luperox® 219M75 polymer initiator

  • Luperox® 219M75 polymer initiator is a free radical initiator for polyvinyl chloride or polyethylene synthesis. The high activity offered by Luperox®219M75 polymer initiator can optimize production of these polymers when combined with other peroxides.

Luperox® 26 polymer initiator

  • Luperox® 26 polymer initiator is useful in a very wide range of high polymer applications including LDPE/EVA or styrenics as well as acrylic coatings, copolymers, and PMMA. Compared with other peroxyesters, the control temperature and SADT of Luperox® 26 polymer initiator is higher allowing for improved ease of use, handling, and transportation.

Luperox® 270 polymer initiator

  • Luperox® 270 polymer initiator is an peroxyester useful in polymerization of LDPE, styrenics, and acrylics. The decomposition materials of Luperox®270 polymer initiator make it a preferable choice over tert-butyl peroxybenzoate. Also, Luperox® 270 polymer initiator can be transported without refrigeration, offering increased flexibility over other peroxyesters.

Luperox® 546M75 polymer initiator

  • Luperox® 546M75 polymer initiator is a high activity peroxyester initiator, typically used for the polymerization of vinyl chloride in emulsion synthesis. The radicals generated are very efficient, therefore conversion of monomer is increased as compared with systems using t-butyl peroxyesters like Luperox® 10.

Luperox® 575 polymer initiator

  • Luperox® 575 polymer initiator is a t-amyl initiator typically used for the production of acrylic resins. The low energy radical produced on decomposition can help improve monomer conversion, while offering lower polydispersity and solution viscosity in the finished resin.

Luperox® P polymer initiator

  • Luperox® P polymer initiator is a versatile molecule for medium to high temperature polymerization of ethylene, styrene, or acrylic monomers. Luperox® P can also be used for redox reactions to cure polyester, vinyl ester, or acrylic resins at room temperature in molded composites applications.

Luperox® TAEC polymer initiator

  • Luperox® TAEC polymer initiator is a tertiary-amyl initiator for use in expandable polystyrene synthesis. the non-aromatic chemistry makes it a good alternative to t-butyl peroxybenzoate for food contact applications. Luperox® TAEC also yields a very efficient radical that improves monomer conversion, reducing residual styrene and improving graft efficiency.

Luperox® TBEC polymer initiator

  • Luperox® TBEC polymer initiator offers as a good mix of thermal stability, crosslink efficiency, and short cure times when used to crosslink ethylene vinyl acetate (EVA) polymers. Luperox® TBEC is also useful for polymerization of styrene for food-contact as it yields non-aromatic fragments upon decomposition.

Luperox® TBICM75 polymer initiator

  • Luperox® TBICM75 polymer initiator is especially useful for curing of traditional or hybrid composite resins with higher vinyl-acetate or styrene content. Luperox® TBICM75 can be used to increase cycle times or reduce any unreacted resin in finished articles.

Applications

  • Coating agent
  • Crosslinking agent
  • Home decorations
  • Paints and vehicle coatings
  • Polymerization and vulcanizing agent

Advantages

  • Peroxyesters offer the widest range of free radical activity out of all the classes of organic peroxides currently used worldwide
