Able to withstand continuous operating temperatures up to 1,560°F, Ultratemp-AL non-wetting carbon fiber reinforced insulating calcium silicate board is noncombustible and asbestos free. Board exhibits prolonged resistance to cracking and disintegration from thermal cycling or action of liquid metal flow, reducing risk of inclusions and casting contamination. Along with resistance to oil penetration, properties include chemical resistance and minimal shrinkage after heating.
