Features Of Disheng UV-326 Benzotriazole UV Absorber

  1. Highly effective UV absorption in the 290–400 nm range, especially strong in the critical UVA-II and UVB regions.

  2. Excellent thermal and hydrolytic stability, maintaining performance during high-temperature processing (e.g., extrusion, injection molding).

  3. Low volatility and minimal migration, ensuring long-term photostabilization in polymeric matrices.

  4. Compatible with a broad spectrum of polymers including polyolefins, ABS, polycarbonate, and engineering thermoplastics.

  5. Non-discoloring and chemically inert under normal use conditions—preserves substrate clarity and color fidelity.

Typical Applications Of Disheng UV-326 Benzotriazole UV Absorber

  1. Automotive interior plastics (dashboards, trim, instrument panels).

  2. Outdoor polymer profiles and building materials (window frames, cladding, roofing membranes).

  3. Packaging films for UV-sensitive contents (pharmaceuticals, agrochemicals, food).

  4. Coatings and clear topcoats for wood, metal, and plastic substrates.

  5. Optical-grade transparent plastics requiring long-term light stability (e.g., lenses, lighting housings).
