Ultra-Thick Viscose-Based Felt
Ultra-thick viscose-based felt has fewer fiber defects. Through controlled weaving, needle-punching and graphitization processes, it achieves low thermal conductivity, suitable density and good oxidation resistance.
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.

Ultra-thick viscose-based felt has fewer fiber defects. Through controlled weaving, needle-punching and graphitization processes, it achieves low thermal conductivity, suitable density and good oxidation resistance.

This new anti-oxidation and corrosion-resistant coating is applied to the surface of rigid felt to improve surface protection in demanding high-temperature service conditions.
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.
