Graftech International

Grafboard(r) is a high-temperature composite insulation material made from flexible graphite and low thermal conductivity carbonaceous interlayers to reduce radiant heat loss that is combined with a rigid graphite backing to reduce convective and conducive heat loss. It is a highly durable material that is resistant to chemical attack, withstands the rigors of an industrial environment without degradation, can provide shorter cycle times and has demonstrated significant energy savings.
