Functions of Light Stabilizer 622

1. Long-term weathering and aging resistance

   It efficiently scavenges photo-oxidative free radicals, and inhibits aging, yellowing, chalking, cracking and mechanical performance decline of plastic and resin products, greatly prolonging outdoor service life.
2. High molecular weight, low migration and no blooming

   With polymeric structure, it features extremely low volatility, good migration resistance and extraction resistance. It will not exude or bloom during long-term application.
3. Excellent thermal stability

   It is stable during high-temperature extrusion, injection molding and spinning processing, without decomposition or discoloration.
4. Wide application range

   Suitable for PE, PP, EVA, PVC, ABS, polyurethane, elastomers, unsaturated resins, coatings and adhesives. Widely used in geomembranes, woven bags, agricultural films, molded parts, wires and cables.
5. Good hydrolysis, acid and alkali resistance

   It has better hydrolysis resistance than low molecular hindered amines, and maintains stable performance under humid, acidic and alkaline conditions.
6. Good synergistic effect

   It can be compounded with UV absorbers and antioxidants to achieve synergistic enhancement of weather resistance and thermal stability.
7. No influence on product appearance

   Light color itself, no negative impact on the transparency, gloss and pigmentation of finished products.
