Product Description

Product Description

High Quality UV 531 99% UV 531 Octabenzone CAS 1843-05-6

Octabenzone (Spectra-Sorb UV 531, MPI Milestab 81) is a UV absorber/screener. It is used to protect polymers (e.g., polyethylene, polypropylene, polyvinylchloride) against damage by UV light.

UV-531 can absorb 240-340 nm ultraviolet light, making it an excellent and efficient anti-aging additive. It has a great protective effect on polymers, helping to reduce color, while delaying yellowing and blocking physical property loss.

Application

Ultraviolet absorber UV-531 is an excellent and efficient anti-aging agent, which can absorb 240-340 nm ultraviolet light, has the characteristics of light color, non-toxic, good compatibility, small migration and easy processing. It has the greatest protective effect on the polymer and helps to reduce color, while delaying yellowing and retarding the loss of physical properties. It is widely used in PE, PVC, PP, PS, PC, plexiglass, polypropylene fiber.And for dry phenolic and alkyd varnishes, polyurethanes, acrylics, epoxies and other air drying products and automotive finishing paints, powder coatings, rubber and other products, to provide them with a good light stabilization effect. Dosage 0.1-0.5%.
