Advanced composite materials

composite hard felt

Graphite hard composite felt is based on the PAN matrix material that after over 2200 C degrees of high temperature graphitization treatment, and then through the special adhesive compound and carbonization treatment. It has a certain rigidity, self support, the proportion of small, low thermal conductivity, no fiber shedding, operating temperature can reach 3200 C degrees. It is suitable for high pressure gas quenching furnace, pressure sintering furnace, multi crystal casting furnace, single crystal growth furnace (sapphire), etc. It can be provided in flat, disc, cylinder and other shapes, has long life-time, and easy to install and remove. The most important characteristic is: high processing temperature, high purity (<200ppm), specially adapts to the high temperature furnace which needs to the extremely furnace body atmosphere.
