Polymer compounders face the continuous challenge of enhancing the performance and lifespan of plastic materials. A critical aspect of this is protecting polymers from the detrimental effects of ultraviolet (UV) radiation. The selection of an appropriate UV stabilizer is a complex decision, influenced by the polymer type, processing conditions, end-use application, and desired performance characteristics. NINGBO INNO PHARMCHEM CO.,LTD., as a leading manufacturer and supplier of polymer additives, offers expertise and high-quality products, including our versatile liquid UV absorber, UV-571, to guide compounders in making informed choices.

Understanding the different types of UV stabilizers is the first step. UV absorbers, like benzotriazoles, function by absorbing UV radiation and dissipating it as heat. Hindered Amine Light Stabilizers (HALS), on the other hand, scavenge free radicals formed during photo-oxidation. Often, a combination of UV absorbers and HALS provides synergistic protection, offering a broader spectrum of defense against UV degradation. For compounders seeking ease of incorporation and broad compatibility, liquid UV absorbers like UV-571 present a significant advantage.

UV-571, a liquid benzotriazole UV absorber, is particularly well-suited for many polymer compounding applications. Its excellent solubility in various solvents and monomers facilitates easy dispersion during the compounding process. This ensures homogeneous distribution, leading to uniform protection across the polymer matrix. Its good thermal stability allows it to withstand the high temperatures often encountered during extrusion and injection molding without significant degradation. Furthermore, its compatibility with a wide range of polymers, including polyolefins, PVC, PUR, and styrenics, makes it a versatile choice for compounders serving diverse markets. When you buy from a reputable manufacturer, you ensure product consistency and performance reliability.

When selecting a UV stabilizer, compounders must consider the end-use environment. For applications involving prolonged outdoor exposure, a combination of UV absorbers and HALS is often recommended. Factors such as the required service life, potential for migration, and regulatory compliance (e.g., food contact approvals) also play a crucial role.
