UV-326 (CAS: 3896-11-5) is a benzotriazole-class ultraviolet (UV) absorber widely used to protect polymers from photodegradation.
It effectively absorbs harmful UV radiation (290–400 nm), extending the lifespan of plastics exposed to sunlight and harsh environments.
Broad-Spectrum Protection – Shields against UV-A and UV-B rays.
Excellent Compatibility – Works with PP, PE, PVC, ABS, coatings, and adhesives.
Minimal Color Impact – Low risk of yellowing, ideal for light-colored or transparent products.
Regulatory Compliance – Meets RoHS, REACH, and FDA (indirect food contact) standards.
