Sunvin 31

Sunvin 31 exhibits very effective protection of polymers against UV lights exposure. UV-531 retards yellowing, embrittlement and mechanical degradation of the polymers when properly used. UV-531 is particularly recommend for the light stabilization of PP, PE and PVC. It is also effective in polycarbonate, polyester, acrylics, EVA, and other polymers.
