UV-327 Application scenarios

1. Polypropylene (PP) Products:

Especially suitable for polypropylene fibers, also used in polypropylene injection molded parts, films, sheets, etc., to improve weather resistance and prevent aging, yellowing, and embrittlement caused by ultraviolet light.

2. Polyethylene (PE) Products:

Suitable for low-density polyethylene (LDPE) and high-density polyethylene (HDPE) films, pipes, containers, etc., enhancing resistance to UV degradation during outdoor use.

3. Polyvinyl Chloride (PVC) Products:

Used in PVC films, sheets, profiles, wire and cable sheaths, etc., to reduce degradation caused by ultraviolet light and maintain the appearance and mechanical properties of the products.

4. Other General Plastics:

Can be used in polystyrene (PS), polymethyl methacrylate (PMMA, acrylic), polyoxymethylene (POM), ABS resin, etc., suitable for transparent and light-colored products without affecting the transparency of the base material.

5. Engineering Plastics and Elastomers:

Suitable for polyurethane (PU), unsaturated polyester, epoxy resin, etc., protecting products from degradation in outdoor or strong UV environments.

6. Coatings and Coating Systems:

Added to solvent-based, water-based, and powder coatings for building exteriors, automotive coatings, industrial anticorrosion coatings, etc., extending the service life of coatings and preventing fading and chalking.

7. Fibers and Textiles:

In addition to polypropylene fibers, it can also be used for UV-resistant finishing of other synthetic fibers and their fabrics, improving the lightfastness of textiles.

8. Masterbatches and Colorants:

Added as a light stabilizing component to plastic masterbatches and colorants, giving colored products both color stability and UV aging resistance.

9. Scientific Research and Standard Materials:

Used in material aging tests and light stabilization mechanism research, and can also be used as a standard for qualitative and quantitative analysis of such substances in environmental monitoring.
