UV-531 Application scenarios

1. Polyolefin Materials:

Used in polyethylene (PE), polypropylene (PP), etc., to delay material yellowing and degradation of physical properties, improving weather resistance. Suitable for various products such as films, pipes, and injection molded parts.

2. Polyvinyl Chloride (PVC):

Suitable for both soft and rigid PVC, reducing degradation, discoloration, and embrittlement caused by ultraviolet light. Commonly used in cable sheathing, window and door profiles, and plastic flooring.

3. General-Purpose and Engineering Plastics:

Applied to polystyrene (PS), polycarbonate (PC), polymethyl methacrylate (PMMA), etc., protecting the appearance and mechanical properties of products and extending their service life.

4. Fibers and Textiles:

Added to polypropylene fibers, ethylene-vinyl acetate (EVA) fibers, etc., to improve the light aging resistance of textiles and maintain color and strength.

5. Paints and Varnishes:

Suitable for drying phenolic varnishes, alkyd varnishes, polyurethane paints, acrylic paints, epoxy paints, etc., as well as automotive refinish paints and powder coatings, slowing down discoloration, loss of gloss, and cracking of the coating.

6. Rubber Products:

Used in polyurethane rubber, etc., to enhance UV aging resistance and extend the outdoor service life of rubber products such as seals, conveyor belts, and hoses.

7. Other Resin Products:

Used in vinyl resins, cellulose plastics, polyesters, polyamides, etc., as a light stabilizer to protect various plastic products.

8. Special Applications:

Can be incorporated into protective films related to electronics and photovoltaics, such as parylene C films, to improve their photostability and meet the protection needs of electronic boards, photovoltaic cells, etc.
