Polyolefins, such as polypropylene (PP) and polyethylene (PE), are ubiquitous in modern life, found in everything from packaging films and automotive components to textiles and construction materials. Their versatility and cost-effectiveness are undeniable, but their susceptibility to photodegradation, particularly from UV radiation, poses a significant challenge. NINGBO INNO PHARMCHEM CO.,LTD. addresses this with HALS 783, a highly effective light stabilizer that plays a critical role in protecting these polymers.

HALS 783 is not just another additive; it's a high-performance synergistic blend of two advanced Hindered Amine Light Stabilizers (HALS): UV-944 and UV-622. This combination leverages the strengths of both components to provide superior UV absorption and radical scavenging capabilities. UV radiation initiates a cascade of chemical reactions within the polymer chain, leading to chain scission, cross-linking, and the formation of chromophores, which manifest as discoloration and loss of mechanical properties. HALS 783 interrupts this degradation cycle by trapping free radicals formed during the photodegradation process, thereby preventing further damage.

The efficacy of HALS 783 is particularly pronounced in polyolefins like PP and PE. These polymers are widely used in applications where they are constantly exposed to sunlight. For instance, PP fibers and films, as well as LDPE, LLDPE, and HDPE films and tapes, benefit immensely from the protection offered by HALS 783. This stabilizer provides excellent long-term thermal stability alongside its UV protection capabilities, ensuring that the polymer maintains its intended properties even under prolonged exposure to heat and light.

Moreover, HALS 783 is characterized by its low volatility and resistance to extraction. This ensures that the protective agent remains within the polymer matrix, providing continuous and reliable stabilization throughout the product's intended service life. This is a crucial factor, as any loss of the additive would compromise the polymer's resistance to UV attack. Manufacturers can also rely on HALS 783 for applications that require indirect food contact approval, underscoring its safety and suitability for a broad range of uses.

By incorporating HALS 783 into their formulations, polymer manufacturers can significantly enhance product durability, reduce warranty claims, and improve customer satisfaction. NINGBO INNO PHARMCHEM CO.,LTD. is proud to offer this advanced solution that safeguards polyolefins against the relentless forces of UV degradation, ensuring performance and longevity.
