Functions of Hindered Amine Light Stabilizer 944 (Chimassorb 944)
- Long-term UV & weathering protectionA high-molecular-weight polymeric HALS that scavenges free radicals generated by UV radiation, effectively preventing photo-degradation, yellowing, chalking, embrittlement and cracking of plastics, rubbers and coatings; significantly extends service life under outdoor exposure.
- Low volatility & migration resistanceExtremely low volatility, excellent resistance to migration and extraction by water/solvents; no blooming or exudation, ensuring long-term stability for outdoor applications.
- Thermal stability & synergistic antioxidant effectProvides thermal-oxidative stability and antioxidant performance; works synergistically with antioxidants and UV absorbers; thermally stable during high-temperature processing.
- Broad compatibility & wide applicabilityCompatible with PP, PE, EVA, TPO, PU, PVC, ABS, polyamide, POM, elastomers and adhesives; ideal for films, fibers, geotextiles, molded parts and cable insulation.
- No impact on color & transparencyLow discoloration, no adverse effect on transparency, gloss and pigmentation; suitable for light-colored and clear products.
- Low toxicity & eco-friendlyCompliant with food contact and environmental regulations; low toxicity, heavy metal-free, safe for use.
