Polyolefins, such as Polyethylene (PE) and Polypropylene (PP), are ubiquitous in modern life, found in everything from packaging films and agricultural products to automotive components and textiles. However, their susceptibility to UV degradation necessitates the use of effective stabilizers. NINGBO INNO PHARMCHEM CO.,LTD. offers Hindered Amine Light Stabilizer 622 (HALS 622) as a premier solution for protecting these widely used polymers.

PE and PP are particularly vulnerable to photodegradation when exposed to sunlight. This can manifest as loss of tensile strength, embrittlement, surface cracking, and discoloration, ultimately reducing the product's service life. HALS 622, a polymeric high molecular weight hindered amine light stabilizer, is specifically engineered to combat these issues. Its unique chemical structure allows it to effectively scavenge free radicals, thereby inhibiting the photo-oxidative degradation process.

The efficacy of HALS 622 in polyolefins is well-documented across various manufacturing processes. For PE applications, including injection molding, rotational molding, films, and tapes, HALS 622 provides crucial UV protection, ensuring that these products maintain their physical properties and appearance over extended periods. Similarly, in PP fibers, its inclusion significantly improves resistance to weathering and light-induced damage.

Furthermore, the low volatility and migration resistance of HALS 622 are advantageous for polyolefin processing. It remains stable at high temperatures encountered during manufacturing, ensuring that its protective qualities are not compromised. This means that whether you are producing thin films or robust molded parts, the UV protection provided by HALS 622 remains consistent and reliable.

NINGBO INNO PHARMCHEM CO.,LTD. understands the critical need for durable and long-lasting polyolefin products. By incorporating Hindered Amine Light Stabilizer 622 into formulations, manufacturers can significantly enhance UV resistance, prevent premature failure, and improve overall product quality. Our commitment is to provide specialized chemical additives that empower industries to create superior, weather-resistant plastic solutions for a wide range of applications.
