UV Absorber UV-1164
2-(2-Hydroxy-4-octyloxyphenyl)-4,6-bis(2,4-dimethylphenyl)-1,3,5-triazine
High-efficiency triazine UVA — the highly compatible choice for polyolefins and engineering plastics.
Product Description
UV-1164 is a hydroxyphenyl-triazine UV absorber efficiently covering 300–400 nm. Its octyloxy side chain yields outstanding compatibility with polyolefins; low volatility and high-heat stability allow high loadings without blooming.
In PP and PE films, tapes and TPO automotive parts, UV-1164 suppresses chalking and fading; it is equally reliable in PA, PC, PET, PBT, ASA, ABS and PMMA. Compounded with HALS such as UV-944 or UV-622 it shows marked synergy.
Typical loadings are 0.2–0.5 wt%. Aolong UV-1164 is ≥98.5% assay with low color contribution and full regulatory documentation.
