Self - Supporting Hard Graphite Felt For Clogged Oilless
Features:
Excellent ablation resistance
Thermal shock resistance
Airflow erosion resistance and thermal insulation performance.
Graphite Hard Felt has the advantages of high rigidity, self-supporting, high strength, no short fiber drop, low thermal conductivity, and other advantages that traditional thermal insulation materials do not have.
