Toyo Tanso Co., Ltd., headquartered in Osaka, Japan, is a global producer and distributor of a wide range of carbon materials. Established in 1941 and originally known as Kondo Carbon Manufacturing Co., Ltd. until its renaming in November 1949, the company provides specialized products for diverse industries worldwide. Its offerings include high-performance isotropic graphite, crucial for applications in the semiconductor, mold, renewable energy, and atomic power sectors. The company also manufactures advanced carbon-carbon composite materials, utilized in electronics, environmental and energy systems, general industrial furnaces, and various transportation modalities such as automobiles. Key products extend to PERMA-FOIL, a flexible graphite sheet designed for sealing applications like automotive gaskets and packing. For demanding environments, Toyo Tanso supplies mechanical carbon, which excels as a sliding component in high-temperature settings, chemical submersion, or where lubrication is impractical; this includes copper-impregnated carbon materials for pantograph sliders. Additionally, it produces carbon brushes for home appliances and power tools. The company's innovative portfolio features PERMA KOTE, a SiC-coated graphite essential for semiconductor manufacturing; PYROGRAPH, a premium high-purity graphite; and GLASTIX KOTE, a graphite substrate enhanced with a glass-like carbon impregnation or coating. Further specialized materials comprise CNovel, a porous carbon; EVEREDKOTE-B, a high-purity isotropic graphite substrate; TaC/Ta Composite EVEREDKOTE-K, a high-purity tantalum; and KLASTA MATE, a unique metal-carbon composite. Beyond material manufacturing, Toyo Tanso offers comprehensive technical services including machining, heat treatment, high-purity processing, surface treatment, impregnation, shaping, and precision measurement.
