In the realm of material science and polymer engineering, safeguarding products against the detrimental effects of ultraviolet (UV) radiation is critical for ensuring longevity and performance. UV-328, a highly effective UV absorber, stands out as a premier choice for a wide range of polymer applications. NINGBO INNO PHARMCHEM CO.,LTD., a prominent manufacturer and supplier, provides insights into why this chemical additive is indispensable for modern material formulations.

Understanding the Chemistry and Functionality of UV-328

UV-328, identified by CAS number 25973-55-1, is a benzotriazole derivative designed to absorb UV radiation primarily in the 270-340 nm wavelength range. This absorption mechanism is vital for protecting polymers from photodegradation, a process that leads to material breakdown, discoloration, and loss of physical properties. As a chemical manufacturer, we emphasize UV-328's core advantages: its excellent compatibility with various polymer matrices, its low volatility, which is crucial during high-temperature processing, and its remarkable resistance to washing, ensuring sustained protection even under demanding environmental conditions. These attributes position it as a superior alternative or complement to similar products in the market.

Applications Across Key Industries

The adaptability of UV-328 makes it a valuable additive for numerous industries. We supply UV-328 for diverse applications including:

  • Polyolefins (PE, PP): Enhancing the weatherability of films, fibers, and molded articles used outdoors.
  • Polyesters (PET, PBT): Protecting automotive components, outdoor signage, and packaging from UV damage.
  • Styrenics (PS, ABS): Maintaining the appearance and structural integrity of consumer electronics housings and automotive interior parts.
  • Polycarbonates (PC): Preserving clarity and impact strength in glazing, lighting, and safety equipment.
  • PVC and Elastomers: Improving the durability of profiles, coatings, and flexible components.
