Luperox® 219M75

Technical Datasheet | Supplied by Arkema
Luperox® 219M75 by Arkema is a 3,5,5-trimethylhexanoyl peroxide. It acts as a polymerization initiator. Compatible with polyvinyl chloride (PVC), low-density polyethylene (LDPE), ethylene-vinyl acetate (EVA), (meth) acrylates, acrylonitrile, acrylonitrile butadiene styrene (ABS) and styrene acrylonitrile (SAN). Its decomposition predominantly gives rise to the formation of selective free radicals appropriate to monomer addition and CO2 that is easy to devolatilize in the monomer recovery step. It can be processed using injection molding. In order to facilitate accurate metering and provide a higher reactor safety, Luperox® 219M75 polymer initiator is preferentially diluted with aliphatic solvents prior to injection. According to its activity it is used in the temperature range of 50°C to 65°C for PVC polymer initiation. Typical initiator concentration ranges between 0.1% and 0.3%.

Hansen Solubility Parameters

[15.5, 1.9, 3.3]
?
[δD - Dispersion force interactions, δP - Polar force interactions, δH - Hydrogen bond force interactions]

Please note, these HSP values are estimations. It is based upon the “like seeks like” principle. It splits an ingredients interactions into three parameters; δD (Dispersion force interactions), δP (Polar forces interactions) and δH (Hydrogen bond force interactions). Hansen Solubility Parameters can help you find a wide range of products that are predicted to be compatible with Luperox® 219M75. A practical determination of these HSP values would provide higher certainty. Learn More.
