In today's demanding market, the longevity and durability of polymer products are paramount. Exposure to ultraviolet (UV) radiation from sunlight is a primary cause of polymer degradation, leading to discoloration, embrittlement, and loss of mechanical properties. This is where high molecular weight polymeric Hindered Amine Light Stabilizers (HALS) play a critical role. As a leading manufacturer and supplier, NINGBO INNO PHARMCHEM CO.,LTD. offers advanced HALS solutions designed to safeguard your materials and enhance product performance.

The mechanism behind HALS involves trapping free radicals generated during the photo-oxidation process. Unlike UV absorbers that screen out UV light, HALS act as radical scavengers, effectively interrupting the degradation chain reaction. Our polymeric HALS, with CAS No. 71878-19-8, are characterized by their high molecular weight. This structural advantage translates into several key benefits for formulators and manufacturers:

• Low Volatility: High molecular weight significantly reduces the likelihood of the stabilizer evaporating during high-temperature processing or over the product's lifespan, ensuring consistent protection.
• Excellent Extraction Resistance: This feature is vital, especially for products exposed to solvents, washing, or weathering. Our polymeric HALS remain within the polymer matrix, providing long-lasting efficacy.
• Broad Compatibility: These stabilizers are compatible with a wide array of polymers, including polyolefins (polypropylene, polyethylene), styrenic copolymers (ABS, ASA), polyamides, polyurethanes, and PVC.
• Efficient UV Stabilization: They offer superior protection for both thin-section applications like films and fibers, and thick-section items such as molded parts.
