250Micron Milky White Insulation Polyester Film

250Micron Milky White Insulation Polyester Film Polyester film is mostly transparent while for thicker films very often a milky film is used for optical reasons. Polyester films have a very good mechanical strength and are resistant against the most oils, grease and solvents used in the transformer- and motor-industry. Under normal circumstances polyester film has a very long life cycle and could be used within a temperature range of - 60°C and + 180°C. Application: - Insulation of  Electrical Motors and Transformer, Capacitors and Electrical Cables- Thermal and Physical barrier- Release Liner Features: - Reduction of Volume and Weight- Higher Insulation Values- Higher Temperature Values- Increased Automatic Production Solutions - Higher temperature class up to 180° C ( class H ) Specification: Thickness :50-350μm Width :350-2000mm (others can be customized ) Other spec can be customized according to client`s requirement.
