TPT SOLAR BACKSHEET
Structure: FEVE/PET/FEVE
Specification:
Thickness and proportion:
0.35mm( 350um) = 25um + 300um+ 25um
0.3mm( 300um) = 25um + 250um+ 25um
Width:500mm-1500mm
Length:100m - 200m
Color:black,white,blue,transparent
Application:
Solar panel = glass+EVA+battery+EVA+TPT backsheet
Advantage:
Using the fluoride coating material, which can resist the erosion of acid (rain), alkali and other chemicals, can prevent the water vapour or other gases.
