E510 white translucency solar photovoltaic cell BOPET films have outstanding mechanical properties, excellent electrical insulation, excellent resistance to water vapor, superior heat and humidity resistance, good tear resistance and a great coating property.
The film is primarily used as the base film to photovoltaic solar cell back boards, which are then further divided into PET films with both side coating fluororesin, PET films with both side coating laminated fluoride, EVA film and other types.
