Insulation press paper of the type having the required quality specifications for electrical insulation purposes are made entirely from vegetable fibres, with a combination of both virgin and recycled fibres. The high purity of the vegetable fibre ensures that the product is totally free from any impurities, and conductive particles in particular. Insulation pressphan paper is available in reel form with a maximum width of 1700 mm and is widely used as electrical insulation between layers of wound coils in electrical motors, in capacitors, transformers and such electrical equipment. We offer these materials in natural brown colour.

This material meets IS 8570-1977 - Type D specifications for press paper for electrical purposes.
