transparent TPT film for solar module backsheet
We have three types of TPT film,black,white,and transparent, main material is stong PET and EVA as back sheet,it is made for the packing of solar cell models, superior light, easy to bend, transmittance is good when comparison to glass.
TPT film is a good packing film for solar cell model,it can supply good protection for solar cells,and it is the most ideal packing material for solar cell package
It has salient product features
1:Thicknss:0.3,0.35,0.4,0.5mm,length:100 meters per roll or 200 meters per roll, max width 1.2 meters
2:have good air separation
3: superior antioxidant, moisture resistance,UV-anti
4:long term of keeping adhesive from hydrolyze
5: good property of electrical insulation
6:superior adhesivement with EVA
7:strong tear strength.
