We specialize in low thermal conductivity carbon felt for high-temperature vacuum furnace insulation up to 2800°C, delivering outstanding energy efficiency and thermal stability.
We offer PAN-based and Rayon-based carbon felts, allowing customers to select the optimal material for insulation performance, purity requirements, and operating temperatures.
Our rayon-based carbon felts provide exceptionally low thermal conductivity and outstanding thermal efficiency at elevated temperatures. Compared to conventional PAN-based grades, they can deliver up to 3–4 times lower thermal conductivity, helping furnace manufacturers reduce energy consumption, improve temperature uniformity, and increase process stability inside the hot zone.
High purity, low ash content, low thermal conductivity and stable performance in high-temperature vacuum furnace insulation systems.
