Hard composite carbon Felt

1. Place of Origin: China (Mainland) 2. Product Name: Hard composite Carbon Felt 3. Model Number: JX-HCF 4. Brand Name: J&X

  The hard composite carbon felt is formed by graphite paper, Pan-based carbon felt, Pan-based carbon fabric by the process of curing sizing and secondary high temperaure purification treatment. The material is superior in ablation resistance performance, thermal shock resistance performance, airflow washing proof performance and heat insulation performance , manily use in the vacuum metallurgy industry furnace, for example, high temperature quenching furnace, low pressure sintering furnace and pressurization vacuum sintering furnace.
