For product formulators and R&D scientists in the plastics industry, selecting the correct UV absorber is paramount for ensuring product longevity and performance. UV Absorber 3030, with its CAS number 178671-58-4, is a high-performance additive that offers distinct chemical advantages, making it a preferred choice for demanding applications.

Chemically, UV Absorber 3030 belongs to the cyanoacrylate class of UV absorbers. Its complex molecular structure, characterized by multiple diphenylacrylate moieties, allows it to efficiently absorb ultraviolet (UV) radiation, particularly in the UVB spectrum, without significantly impacting the visible light transmission. This property is critical for transparent polymer applications where clarity is essential, such as in PC sheets and films.

A key chemical attribute that distinguishes UV Absorber 3030 is its high molecular weight. This contributes directly to its low volatility and excellent thermal stability. Unlike lower molecular weight UV absorbers that can evaporate or degrade during high-temperature polymer processing (e.g., extrusion, injection molding), UV Absorber 3030 remains largely intact, providing sustained protection. This makes it an attractive option for manufacturers looking to buy UV Absorber 3030 from reliable suppliers, especially those based in China who can offer cost-effective solutions.

The anti-yellowing capabilities of UV Absorber 3030 are also a direct result of its chemical structure and its ability to effectively quench free radicals generated by UV exposure. By absorbing UV photons and dissipating the energy as heat, it prevents the photo-oxidation processes that lead to polymer yellowing and embrittlement. This makes it invaluable for products intended for outdoor use or prolonged exposure to light sources.

When evaluating UV Absorber 3030, formulators should consider its compatibility with various polymer matrices and its synergistic potential. Often, it is used in conjunction with Hindered Amine Light Stabilizers (HALS) to provide a comprehensive protection system. If you are a research scientist or a procurement manager looking to purchase this advanced chemical, understanding these chemical properties will help you make an informed decision. Engaging with a reputable manufacturer for quotes and technical data is a recommended step.
