Chiguard® 5540

Technical Datasheet | Supplied by Chitec Technology
HSP Distance with Quent® TPP: 2.8
2,4-Di-tert-butylphenyl 3,5-di-tert-butyl-4-hydroxybenzoate. Acts as a UV light absorber (benzoate ester). Provides very good thermal stability and preserves tensile and elongation properties of the polymers to protect the surface from cracking. Doesn’t add any initial color to the substrate or polymer, as it doesn't absorb visible light. Particularly useful in stabilizing pigmented polymers, especially in cases where the pigment itself contributes to the degradation of the polymer.

Hansen Solubility Parameters

[16.8, 1.2, 2.6]
?
[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 Chiguard® 5540. A practical determination of these HSP values would provide higher certainty. Learn More.
