In motor applications, selected types of polyester film can be used for ground insulation as slot liners and wedges, as well as phase insulation. In wire and cable applications, it is ideal for mechanical barriers.

In addition, specialized polyester film can be used in transformer and high-voltage distribution equipment to wrap the conductors. They are effective for use in hermetic applications with refrigerator and air conditioner motor / compressor assemblies.

Available

In rolls, in strips
