The performance and longevity of many industrial materials, particularly plastics and coatings, are significantly influenced by their ability to withstand ultraviolet (UV) radiation. UV Absorber 327, a benzotriazole derivative, is a key chemical additive designed to provide this crucial protection. Understanding its chemical properties is fundamental to appreciating its role in enhancing material durability.

Chemically, UV Absorber 327 has a molecular formula of C20H24ClN3O and a molecular weight of approximately 357.9 g/mol. Its structure allows it to efficiently absorb UV radiation, acting as a screen that intercepts harmful wavelengths before they can initiate photodegradation in the host material. The specific absorption spectrum, typically ranging from 270 to 400 nm, covers the most damaging parts of the UV spectrum, making it highly effective in preventing issues like color change, loss of mechanical strength, and surface degradation.

The physical characteristics of UV Absorber 327 are equally important for its application. It is typically supplied as a light yellow crystalline powder. This form factor, combined with its low volatility, ensures that it can be easily incorporated into various polymer matrices during processing without significant loss. The compound also exhibits excellent thermal stability, meaning it can endure the high temperatures often used in plastic manufacturing processes, such as extrusion and injection molding, without decomposing. This stability is critical for ensuring consistent, long-term protection.

UV Absorber 327 finds widespread application across numerous industries. Its compatibility with a broad range of polymers, including polyolefins, PVC, ABS resins, and polycarbonates, makes it a versatile choice. It is particularly noted for its suitability in polypropylene fibers, contributing to their durability and resistance to weathering. In coatings and adhesives, it helps to maintain film integrity and prevent delamination caused by UV exposure. The product's ability to hardly absorb visible light is a key benefit for applications where color and clarity are important, such as in clear plastics or light-colored coatings.

When manufacturers seek to buy UV Absorber 327, they are looking for a reliable additive that delivers consistent performance. Partnering with reputable chemical suppliers such as Ningbo Inno Pharmchem Co., Ltd. ensures access to high-quality products that meet stringent specifications. By understanding the chemical properties and application benefits of UV Absorber 327, businesses can effectively leverage this additive to protect their products and enhance their market appeal through superior durability.
