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.
