Hard composite Graphite Felt (JX-HGF)6
The hard composite graphite felt is formed by graphite paper, PAN-based graphite felt, PAN-based carbon fabric by the process of curing sizing and secondary high temperature purification treatment. The material has high carbon content and superior in ablation resistance performance, thermal shock resistance performance, airflow washing proof performance and heat insulation performance. It’s mainly used in ultra-high-temperature high pressure vacuum sintering furnace, solar industry, semiconductor industry and electronic industry.
