UV absorbers UV-531 is a high performance and efficient Anti-aging agents, can absorb UV 240-340 nanometers, with light color, nontoxic, good compatibility, small relocation and easy to process characteristics. It is the largest polymer protective effect, and help to reduce the color, while delaying and obstructing the yellowed loss of physical properties. It is widely used to PE, PVC, PP, PS, PC, PMMA, PP fibers and ethylene |
