UV-326 Application scenarios

1. Polyolefin Products:

Used in polyethylene (PE), polypropylene (PP), etc., suitable for processing methods such as film blowing, injection molding, and extrusion, improving the weather resistance and anti-yellowing properties of outdoor products (such as agricultural films, pipes, and containers).

2. Polyvinyl Chloride (PVC):

Used in PVC sheets, profiles, films, wire and cable sheaths, etc., inhibiting UV-induced degradation and extending service life.

3. Engineering Plastics:

Suitable for polycarbonate (PC), polyamide (PA), ABS, polyester (PET/PBT), epoxy resins, etc., especially suitable for transparent/light-colored products, such as automotive parts, electronic housings, and optical components.

4. Coatings and Adhesives:

Used in solvent-based and water-based coatings (such as automotive paints, industrial anticorrosive paints, and building exterior paints) and adhesives, preventing coating chalking, discoloration, and loss of gloss, and improving weather resistance.

5. Synthetic Fibers and Textiles:

Added to the spinning process of polyester, nylon, and other fibers, or used in textile finishing, improving the UV aging resistance and lightfastness of fabrics, and reducing fading.

6. Rubber Products:

Used in natural rubber and synthetic rubber (such as styrene-butadiene rubber, neoprene), protecting rubber products (such as seals, conveyor belts, and outdoor rubber components) from UV aging, maintaining elasticity and strength.

7. Photosensitive Materials and Inks:

Used as a light stabilizer in photosensitive materials and printing inks, preventing light-induced chemical changes and improving product storage stability and service life.

8. Food Contact Materials:

Used as an additive in food contact materials and products, for plastic packaging, containers, etc., that meet compliance requirements.
