Doverphos® S-9228T

HSP Distance with Dragonox -1010: 1.0
Doverphos® S-9228T by Dover (ICC Industries) is bis (2,4-dicumylphenyl) pentaerythritol diphosphite with 1% triisopropanol amine. It is free-flowing solid phosphite antioxidant. Has outstanding hydrolytic stability. Possesses outstanding performance in stabilizing polymers against melt flow degradation and color change. Doverphos® S-9228T in polymer systems has improved permanence where other phosphites may lose activity even when encapsulated in the polymer or in one-pack blends. Doverphos® S-9228T does not hydrolyze and cause black specks as do other phosphites.

Hansen Solubility Parameters

[19.2, 0.1, 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 Doverphos® S-9228T. A practical determination of these HSP values would provide higher certainty. Learn More.
