The selection of appropriate additives is critical for ensuring the performance and longevity of plastic products, especially those intended for outdoor use or prolonged exposure to light. For polyolefins like polypropylene (PP) and polyethylene (PE), UV stabilization is paramount to prevent degradation and maintain desirable properties. This guide from NINGBO INNO PHARMCHEM CO.,LTD. aims to shed light on the crucial role of Hindered Amine Light Stabilizers (HALS) and help manufacturers make informed choices for their applications.

Polyolefins are susceptible to photodegradation, a process that breaks down polymer chains, leading to loss of color, mechanical strength, and flexibility. UV stabilizers work to counteract these effects. Among the most effective are HALS, which function by scavenging free radicals generated during the UV exposure cycle. This regenerative mechanism allows them to provide long-lasting protection, making them an excellent choice for demanding applications. Our Hindered Amine Light Stabilizer 3346, for instance, is a high molecular weight, polymeric HALS that offers exceptional performance.

When selecting a light stabilizer for polyolefins, several factors should be considered: the specific type of polyolefin, the intended application, the expected service life, and the environmental conditions. High molecular weight HALS, like our 3346, are often preferred for applications requiring extended durability due to their low volatility and resistance to migration. This ensures consistent protection throughout the product's lifespan, contributing to effective UV stabilization for PP and PE. The polymeric nature of our stabilizer also means it has excellent compatibility, minimizing adverse effects on processing and product aesthetics.
