This product has good dielectric and high mechanical properties.

1 technical requirements 1.1 appearance The film is supplied in roll form. Its surface should be flat and smooth. The film should be free of defects such as wrinkles, avulsions, grains, bubbles, holes, and contaminations. Edges of rolls should show clean cuts.

1.2 thickness and tolerance Recommended nominal thickness is as follows: 0.025mm,0.050mm,0.075mm,0.100mm,0.125mm,0.150mm,0.188mm,0.200mm,0.250mm,0.300mm,0.350mm. Special requirements for thickness can be settled upon negotiation.

Less than 0.100mm tolerance 5% 0.100mm--0.300mm tolerance 4% 0.300mm--0.350mm tolerance 6% 2.6020 is a transparent film.6021 is a milky white film.

This film is widely used for electrical insulation, such as slot insulation, interphase insulation and liner insulation in electric motor, wrapping insulation for coils and cables, as well as making insulating flexible laminates. Avoid crackles, scratches, contamination of dust and oil while being slit and/or used.
