Composite paper-polyester films

6520 Composite polyester paper films are a composite of 6020 polyester film and paper. These films are used in electrical machinery and equipment as a gap or insulation insert.

Characteristics: Smooth surface, inflexibility, does not consist under the influence of bending.

Width: 1000±20mm, 40-60kg / roll

Material requirements:
Thickness: 0.15; 0,17; 0,20; 0,25; 0,30; 0.35mm.
Penetration volt: non-bendable films ≥6.0 kV
Bendable films ≥5.0 kV

The film is leaked at temperatures greater than 130°C ±2°C for 10 minutes.
