Polyester Film for Solar Cell Backsheet

Description:

Polyester Film for Solar Cell Backsheet is a biaxially oriented polyethylene terephthalate (PET) film made of modified polyethylene terephthalate resin and special additive.

This film has excellent hydrolysis resistance, low vapor transmission, excellent physical and mechanical properties, good thermal resistance, dimensional stability, dielectric properties, flame resistance, and processing properties.

Application:

Polyester Film for Solar Cell Backsheet is being widely used in applications that require low vapor transmission film such as solar battery backing film.
