Description:6520 polyester film composite electrical insulation paper is made of electrical fish paper and polyester film layer formed by adhesive bonding. this material has a excellent performance in both electrical and mechanical properties. The used adhesive is acid-free and temperature resistant. It has excellent electrical and mechanical properties, it can be used for low-voltage motors, electrical insulation in a groove, insulation and cushioning interterm insulation.
It enables easy processing on automatic machines.
It can be used as slot and phase insulation in low voltage machines or as interlayer insulation in transformers.
Special thicknesses or combinations can be supplied according to customer.
Products can be supplied in rolls, sheet, tapes or shapes according to customer requests.
According to different thicknesses of Polyester film, 6520/6521 Polyester film/Presspaper can be divided into 6520-23 / 6520-36 / 6520-50.
