Polymer materials are ubiquitous in modern life, found in everything from automotive components and construction materials to textiles and packaging. However, their exposure to ultraviolet (UV) radiation from sunlight can lead to significant degradation, resulting in loss of mechanical strength, discoloration, cracking, and reduced lifespan. To combat these detrimental effects, the integration of effective light stabilizers is crucial.

NINGBO INNO PHARMCHEM CO.,LTD. is pleased to highlight UV Light Stabilizer 944, a highly effective hindered amine light stabilizer (HALS) designed to provide superior protection against UV-induced degradation in a wide range of polymer systems. Also known as HALS 944, this advanced additive, identified by CAS numbers 71878-19-8 and 70624-18-9 (US), is a polymeric HALS known for its exceptional performance and durability.

UV Light Stabilizer 944 functions by scavenging free radicals formed during the photo-oxidation process of polymers. Unlike UV absorbers that block incoming UV light, HALS additives actively intervene in the degradation cycle, offering long-term protection. This mechanism makes HALS 944 particularly effective in thick sections and pigmented applications where UV absorbers may be less efficient. Its polymeric structure contributes to low volatility, preventing migration and loss from the polymer matrix over time, thus ensuring sustained protection throughout the product's service life. Additionally, HALS 944 exhibits good thermal stability and works synergistically with other additives like antioxidants and UV absorbers to achieve optimal stabilization performance.

The versatility of UV Light Stabilizer 944 makes it suitable for a broad spectrum of polymer applications. It is widely used in polyolefins such as polypropylene (PP), polyethylene (PE), including HDPE, LDPE, and LLDPE, as well as in PEX, PPE, POM, PA, PU, and PVC. Its integration helps to significantly extend the outdoor weathering resistance and overall lifespan of products made from these materials, preserving their aesthetic appearance and functional properties.

NINGBO INNO PHARMCHEM CO.,LTD. offers UV Light Stabilizer 944 as a white powder or granule, with high purity (≥99%). Typical specifications include a melting point range of 110-130 °C, low volatile matter (≤0.5%), and minimal ash content (≤0.1%). The product is packaged typically in 25kg cartons with an inner plastic bag or can be customized according to specific customer requirements. Proper storage in a dry, well-ventilated place, away from direct sunlight, moisture, high temperature, and substances containing sulfur or halogen, is recommended to maintain product quality.
