Toyo Tanso's PERMA-FOIL® graphite sheets have high cushioning properties that allow them to adhere closely to a product and rapidly transmit heat from a heat source to a heat sink. PERMA-FOIL® has been the focus of a lot of attention as a heat countermeasure in semiconductor and electronic component manufacturing processes that require cooling.

PERMA-FOIL® is classified as graphite, meaning that it can be used between -200°C and 3200°C in a non-oxidizing atmosphere。 As it also features strong resistance to acids and alkalis, PERMA-FOIL® is often used in atmospheres where other materials cannot be used。

Toyo Tanso offers a range of high-purity products and various grades of different thicknesses and densities, allowing us to propose products to suit your application, conditions, or atmosphere.
