Our graphite insulation is made in the U.S.A. and is used as insulation for vacuum and protective atmosphere process furnaces. Our combination of high-quality rayon and pitch fiber gives our graphite insulation superior insulating values and strength. Our insulation is treated at temperatures above 2,000°C to ensure its temperature stability and the absence of outgassing. Impurity levels below 20 ppm can be achieved through our in-house purification process. The material can be easily cut or machined in a variety of complex shapes and sizes. Graphite Insulation can be sealed with our BC-501 graphite coating, or by adhering graphite foil to the surface with our BC-628 graphite adhesive.
