Polyolefins, such as polypropylene (PP) and polyethylene (PE), are ubiquitous in modern life, found in everything from packaging and automotive parts to textiles and construction materials. Their excellent mechanical properties, low cost, and ease of processing make them highly desirable. However, polyolefins are inherently susceptible to degradation by UV radiation, which can lead to surface cracking, chalking, color fading, and a loss of tensile strength. To mitigate these effects and ensure the long-term performance of polyolefin products, the incorporation of UV stabilizers is essential. NINGBO INNO PHARMCHEM CO.,LTD. offers UV Absorber 326, a highly effective solution specifically suited for these versatile polymers.

UV Absorber 326, identified by its CAS number 3896-11-5, is a benzotriazole-based UV absorber renowned for its strong absorption in the critical 300-400 nm UV range. This means it effectively intercepts and neutralizes damaging UV light before it can initiate photo-oxidative degradation within the polyolefin matrix. A key attribute of UV Absorber 326 is its excellent compatibility with polyolefins, allowing for uniform dispersion and consistent protection throughout the material. Furthermore, it exhibits low volatility, which is crucial for maintaining its concentration and efficacy during high-temperature processing common in polyolefin manufacturing.

The benefits of using UV Absorber 326 in polyolefins are substantial. It significantly improves the weatherability and lightfastness of these materials, ensuring that products retain their intended color, gloss, and mechanical properties even after prolonged exposure to sunlight. This is vital for applications like outdoor furniture, automotive components, agricultural films, and construction profiles, where durability is paramount. As a leading manufacturer and supplier, we provide UV Absorber 326 with high purity and reliable performance, ensuring you can buy with confidence.

The recommended addition level for UV Absorber 326 in polyolefins typically ranges from 0.2% to 1.0% by weight, depending on the specific grade of polyolefin, the thickness of the product, and the expected intensity and duration of UV exposure. For enhanced protection, especially in demanding outdoor applications, UV Absorber 326 can be effectively combined with other polymer additives, such as hindered amine light stabilizers (HALS) and antioxidants. This synergistic approach provides comprehensive stabilization against UV light, heat, and oxidation, leading to a significant extension of the product's service life.
