Classification Temperature °F °C
Service Temperature °F °C

ALTRA KVS AND KVR HIGH-DENSITY VACUUM-FORMED BOARDSALTRA high-density vacuum-formed board products are available in formulations for service temperatures up to 1800C. ALTRA high-density boards are available for high-temperature, oxidizing environments (KVS) and high-temperature, reducing environments (KVR). ALTRA boards are formed from alumina or mullite polycrystalline fibers with appropriate inorganic and organic binders. All grades are pre-fired to 1000C or greater, resulting in an organic-free composition. Possible applications include furnace hearth plates and low mass sintering setters.
