Our graphite insulation, proudly made in the U.S.A., is specifically designed for use in vacuum and protective atmosphere process furnaces. By combining high-quality rayon and pitch fibers, our insulation delivers superior thermal performance and strength. It is treated at temperatures exceeding 2,000°C to ensure optimal temperature stability and eliminate outgassing. Through our in-house purification process, we can achieve impurity levels below 20 ppm. The material is easily machinable and can be custom cut into complex shapes and sizes to meet specific application needs. Additionally, our graphite insulation can be sealed with BC-501 graphite coating or reinforced with graphite foil using our BC-628 adhesive for enhanced durability.
