Mylar: compound upgrade to meet the needs of electrical equipment

The composite application of polyester film in the field of electrical insulation has become the mainstream of development, and the 6520 series composite insulation materials are in high demand in the market, which is composed of sulfate wood pulp insulation paper and high-temperature resistant PET film, with a breakdown voltage of not less than 8KV, and still maintains good insulation performance after bending. This type of product is suitable for motor stator windings, dry-type transformer coils and other scenarios, with a heat resistance level of 120°C, and complies with EU RoHs environmental protection standards. With the upgrading of new energy power generation equipment and high-end motors, polyester film is iterating in the direction of thinness and high adhesion, and polyester matrix composite products will account for more than 30% of the new insulation material market in 2023.
