Sunvin 21

1 of 11 products in this brand
Sunvin 21 is a benzotriazole type UV absorber. Characterized by its strong, broad range UV absorption property, UV-P brings an excellent photostability to polymers against UV light exposure in many ways i.e. retarding color yellowing , preventing embrittlement, maintaining of mechanical properties etc. UV-P is particularly effective in styrenic polymers, PVC, unsaturated polyesters, polyurethanes, acrylic polymers and polycarbonates.
