In the competitive landscape of polymer manufacturing, extending the service life and maintaining the performance of plastic products under environmental stress is a constant challenge. Ultraviolet (UV) radiation is a primary culprit behind polymer degradation, leading to loss of mechanical properties and aesthetic appeal. To address this, advanced stabilization technologies are employed, with Hindered Amine Light Stabilizers (HALS) being a cornerstone. NINGBO INNO PHARMCHEM CO.,LTD. specializes in providing high-performance HALS, particularly those with high molecular weight, such as our Hindered Amine Light Stabilizer 3346.

The distinction between low molecular weight and high molecular weight HALS is significant, especially concerning their performance and application longevity. While low molecular weight HALS can be effective, they are prone to migration and volatilization, diminishing their protective capabilities over time and under thermal stress. High molecular weight HALS, such as our 3346, overcome these limitations. Their larger molecular size inherently reduces their tendency to migrate or evaporate, ensuring that the stabilizing agents remain integrated within the polymer matrix for extended periods.

This enhanced permanence is crucial for achieving truly long-term stability for plastics. It means that even in demanding applications, such as automotive exteriors, construction materials, or agricultural films, the polymer can rely on consistent protection against photo-oxidation. The benefits extend to processing as well; high molecular weight HALS typically exhibit lower color contribution and better compatibility with a wider range of polymers, including polyolefins. This allows for greater formulation flexibility and ensures that the visual appeal of the final product is not compromised.

As a leading manufacturer in China, NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to producing high-quality polymeric light stabilizers that meet global standards.
