TJ400 & TJ800 are the typical products from the POE encapsulating Film series, developed by Sinopoly Materials. TJ400 is the standard one, with high transparency, normally for the front side, while TJ800 is the UV cut-off type, targeting the back side. Both of them have excellent barrier properties, anti-PID performance, good weatherability and adhesion strength retention, which are perfect for both PERC and TOPCON modules. It’s also acceptable for tailor made grades according to your given requirements.
