        Polyester Film

        Polyester Film

        詳細說明



        Description

        POLYESTER FILM is a polyethylene terephtalate based transparent flexible polyester film which

        becomes cloudy with increasing thickness.     

                                                                                

        Properties

        POLYESTER FILM provides the electrical industry with unique design and construction options due to the outstanding balance of its electrical properties in combination with chemical, thermal and physical properties.

        The polyester film is characterised by its excellent resistance to moisture and common solvents.

        It can be used at temperature of -70oC to 150oC. since it does not contain any softening agents, it does not become brittle with age when use in normal conditions.


        Application 

        According to the manufacturers specification POLYESTER FILM is used in class B (130oC) systems by numerous manufacturers of electrical motors.  POLYESTER FILM is use as slot insulation, phase insulation and wedges for motors and generators.  POLYESTER FILM is use as core, interlayer and final insulation for transformers, chokes and relays.
