Milestab 144

Technical Datasheet | Supplied by MPI Chemie
Bis(1,2,2,6,6-pentamethyl-4-piperidinyl)-[[3,5-bis(1,1-dimethylethyl)-4-hydroxyphenyl]methyl]butylmalonate. Acts as a light stabilizer. It prevents the oxidation, chain fission, uncontrolled recombinations and cross-linking reactions that are caused by photo-oxidation of polymers. It dissipates the absorbed light energy from UV rays as heat by reversible intramolecular proton transfer. This reduces the absorption of UV rays by the polymer matrix and hence reduces the rate of weathering.

Hansen Solubility Parameters

[17.5, 1.3, 0.1]
?
[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 Milestab 144. A practical determination of these HSP values would provide higher certainty. Learn More.
