Thermally Insulating paper

 
             

Product information

The insulating thermally paper is manufactured from 100% high-quality sulfate insulating wood pulp under a special process according to Siemens TUN901156 Standard.  This paper is highly refined and cleaned to ensure uniform thickness and formation. Pinholes, undispersed fiber bundles and tiny defects, if any, are minimized to meet the safety requirements in the manufacturing and applications of transformers and cables.  It is heat and age-resistance insulating grade paper well suited for making electromagnetic wires of transformers and other electrical insulating equipments.  This paper has stable electrical and chemical properties, and high physical strength to meet the exacting needs of our valued customers. The papers are available in nominal thicknesses from 60um to 105um, and in continuous rolls up to the widths of 625mm and 960mm (the roll diameter being 680mm-730mm), or other customized diameter and width per the purchase contracts.
