J400P & J800P are the typical products from the anti-PID EVA encapsulating Film series, developed by Sinopoly Materials. J400P is the standard one, with high transparency, normally for the front side, while J800P is the UV cut-off type, targeting the back side. Both of them have excellent anti-PID performance, snail grain resistance, good weatherability and adhesion strength retention. It’s also acceptable for tailor made grades according to your given requirements.
