Quent® 618

Distearyl pentaerythritol diphosphite. Acts as a secondary high performance antioxidant for organic polymers. Provides very good color protection during thermal processing of polymers. Shows synergism when used with light stabilizer such as benzophenone and benzotriazole. Offers reduced discoloration of polymers containing pigments such as TiO2, and of polymers that are stabilized with sulfur–containing nickel organic complex and are processed at high temperature. Used for applications including polyolefins, elastomers, polyesters, styrenics, and engineering thermoplastics.

Hansen Solubility Parameters

[14, 0.3, 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 Quent® 618. A practical determination of these HSP values would provide higher certainty. Learn More.
