Insulation Kraft Papers of the type having the required quality specifications for electrical insulation purposes are made entirely from imported virgin fibres. The high purity of the imported virgin fibers ensures that the product is totally free from any impurities and conductive particles in particular. Insulation Kraft Paper is available in roll form with a maximum width of 1500 mm and is widely used as electrical insulation wrap on aluminum and copper wires by conductor manufacturers, electrical insulation between layers of wound coils in electrical motors, in capacitors, transformers and such electrical equipment. We offer these materials in natural brown finish in 2.0 Mil 2.5 Mil, 4.0 Mil and 5.0 Mil.

The material meets IEC PUB: 60554-3-5 specifications for insulation paper for electrical purposes.
