UV absorber UV-P

UV absorber UV-P also known as Tinuvin P,Linsorb UV P

UV absorber UV-P is a high efficient UV absorber, which can effectively absorb 270-380 nm UV light.

Odorless, good thermo stability under high temperature.Non-flammable, non-explosive, non-toxic, harmless to health.

This product almost does not absorb visible light, particularly applicable to colorless and light-colored products.

Advantages & Features

  • Strong UV absorption
    UV absorber UV-P delivers strong absorption in the 300–400 nm range, helping effectively protect materials from UV radiation.
  • Excellent photostability
    It offers a high degree of photostability during long periods of light exposure, making it suitable for outdoor and light-sensitive applications.
  • Good light stability for polymers
    UV-P is designed to improve light stability and help reduce UV-related degradation such as discoloration, loss of appearance, and material aging in polymers.
  • Easy to position in formulations
    As a benzotriazole UV absorber, UV-P is a proven additive choice for improving durability in plastics and other organic substrates.
