Hongchang product families cover flexible carbon fiber felt, graphite felt, rigid composite felt, carbon cloth, carbon rope, graphite paper, battery felt, quartz crucibles and coating solutions for photovoltaic, semiconductor, vacuum furnace and energy applications.
Browse Hongchang material families for high-temperature insulation, thermal field protection and energy equipment use.
PAN-based rigid composite felt offers good strength, low thermal conductivity, ablation resistance, oxidation resistance, low expansion coefficient and good thermal shock performance. It is used in single-crystal furnaces, polycrystalline furnaces, powder m…
Integral felt is supplied for high-temperature insulation applications where a formed felt structure is required.
Viscose-based carbon fiber graphite felt has fewer fiber defects. Through controlled weaving, needle-punching and graphitization processes, the product achieves low thermal conductivity, suitable density and good oxidation resistance.
Pre-oxidized fiber graphite felt is made from polyacrylonitrile-based fiber through pre-oxidation, crimping, cutting, needle-punching, carbonization and graphitization. Compared with PAN-based graphite felt, it offers lower density, better softness and lowe…
PAN-based carbon fiber felt is made from polyacrylonitrile-based fiber through nonwoven and needle-punching processes. After controlled pre-oxidation, carbonization and graphitization, it becomes a mature high-temperature thermal insulation material.
Share the application, furnace type, working temperature, thickness, width, purity and installation conditions. Hongchang can help match the suitable felt, composite insulation or carbon fiber material family.
