2-(2-Hydroxy-5-methyl-phenyl)-benzotriazole lower price UV-P high purity UV-P
1. Unsaturated Polyester : 0.2-0.5wt% based on polymer weight
2. PVC: Rigid PVC : 0.2-0.5wt% based on polymer weight ; Plasticized PVC : 0.1-0.3wt% based
on polymer weight
3. Polyurethane : 0.2-1.0wt% based on polymer weight
4. Polyamide : 0.2-0.5wt% based on polymer weight
It is a benzotriazole type ultraviolet light absorber (UVA), imparting good light stability
for plastics and other organic polymers. UV-P protects polymers as well as organic pigments
from UV radiation helping to preserve the original appearance and physical integrity of engi-
-neered plastics, elastomers, PVC, adhesives, and polyurethanes during outdoor weathering.
