UV Absorber 329

Technical Datasheet | Supplied by Disheng Technology
UV Absorber 329 is a 2- (2'-Hydroxy-5'-tert-octylphenyl) benzotriazole by Disheng Technology. It acts as a highly efficient UV absorber that can absorb 270-380 nm UV light and also acts as an age-preventing agent. It offers non-flammability, non-explosiveness, non-toxicity and no harm to health. It is recommended for colorless and light-colored products. It is compatible with polyester, rigid PVC, PS, PMMA, PC, polyolefin and ABS resin. It is suitable for transparent products and engineering plastics under high temperature processing. The dosage level of UV Absorber 329 is 0.2-0.5% for PS, 0.3-0.5% for ABS, 0.2-0.4% for PE, 0.2-0.5% for PVC and 0.3-0.5% for polyester.

Hansen Solubility Parameters

[18.3, 4.6, 4.8]
[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 UV Absorber 329. A practical determination of these HSP values would provide higher certainty. Learn More.
