Keeping abreast of times, business markets demanded a finer grade carbon of more stable properties. Ahead of the rest of the industry, Toyo Tanso developed an "isotropic graphite" which is pressed by Cold Isostatic Press, having superfine isotropic microstructure. We have established world level technology that enables this isotropic graphite to fully exhibit its superior properties in the fields of nuclear power which requires high reliability, electrical discharge processing where accuracy is everything, and semiconductors which supports today's hi-tech wave.

C/C composite is a carbon-carbon composite material reinforced by high strength carbon fiber for the purpose of improving strength and shock resistance of carbon materials. It is a hi-tech carbon material that is equally selected for general industrial use as it is used in advanced technological fields such as aerospace and semiconductor manufacture. To meet the diversified needs of the 21st century, the Toyo Tanso Group offers a filament winding type in our FW Series, a two-dimensional type in our CX Series and special grade composites.

PERMA-FOIL® is a flexible graphite sheet made from specially processed natural graphite without use of a binder. Special processing developed by us gives it a flexibility and compression recovery not found with conventional graphite products. These qualities ensure a snug fit with contacting parts, therefore it is widely used as a seal, to note automotive gaskets and packing.

Taking advantage of the self-lubrication and chemical and heat resistance features of carbon, mechanical carbon is used for sliding parts in high temperature environments where metals cannot be used as well as for submersion in chemicals and in fields where lubricated parts cannot be used. Already, our KC, TUG and IG Series are widely used and highly evaluated in a broad range of industries. Our copper-impregnated carbon materials for a pantograph slider are extending the life of wiring.

Because of the sliding contact they make, motor brushes play an important part in flowing electric current between stationary and rotary parts. Brush performance greatly determines the performance of rotary equipment such as motors and generators, therefore brushes must be carefully selected. Toyo Tanso's brushes are active across a broad span of industry, centered primarily on small brushes for home appliances and power tools.
