PERMA-FOIL™ is a generic term for the flexible graphite sheet that Toyo Tanso developed through our original manufacturing technology. It is a sheet graphite product that is formed using select acid treated natural graphite, which is then compressed after undergoing high temperature expansion. Only...
In this context, Toyo Tanso was the pioneer in our industry in developing "isotropic graphite". This is a graphite material with micro particles and an isotropic structure and properties which created through the cold isostatic pressing(CIP) of micro particles. Our isotropic graphite products are ...
As it is classified as graphite, PERMA-FOIL™ can also be used between -200°C and 3200°C in a non-oxidizing atmosphere and features strong resistance to acids and alkalis. Toyo Tanso offers various grades of different thicknesses and densities, allowing us to propose products to suit ...
