Polyolefins, such as polyethylene (PE) and polypropylene (PP), are ubiquitous in modern life, finding applications in everything from packaging and agricultural films to automotive parts and consumer goods. However, these versatile polymers are susceptible to degradation when exposed to environmental factors, particularly UV radiation. This degradation can manifest as discoloration, surface cracking, and a loss of mechanical properties, severely limiting their outdoor lifespan and performance.

To address this challenge, the integration of effective light stabilizers is crucial. Among the most potent are Hindered Amine Light Stabilizers (HALS), and specifically, Light Stabilizer 3346 stands out for its performance and compatibility with polyolefins. As a high molecular weight HALS, product 3346 offers low volatility, meaning it remains within the polymer matrix even at elevated processing temperatures, ensuring long-term protection. Its low color contribution is also a significant advantage, preventing unwanted hues in the final product.

What makes Light Stabilizer 3346 particularly valuable for polyolefin applications is its excellent compatibility and solubility/migration balance. This ensures that the stabilizer is evenly distributed throughout the polymer, providing consistent protection across films, fibers, and molded parts. Whether used in thin agricultural films that endure intense sunlight or in thicker injection-molded components for outdoor use, this HALS effectively prevents photodegradation, maintaining the material's integrity and appearance.
