About Hongchang

Thermal-Field Insulation, Quartz Products And Flow Battery Materials

Anhui Hongchang New Materials provides thermal-field insulation products, quartz consumables and flow battery carbon felt materials for photovoltaic, semiconductor and energy storage industries.

PhotovoltaicSemiconductorEnergy StorageHigh-Temperature Systems

Hongchang manufactures carbon fiber graphite felt, high-purity graphite felt, rigid composite felt, carbon cloth, carbon rope, graphite paper, quartz crucibles, quartz guide tubes, flow battery felt and developing coating solutions. The company serves high-temperature thermal systems while extending its material capability into quartz products and new energy storage applications.

Instead of presenting itself as a general carbon materials supplier, Hongchang is positioned around a clearer industrial scope: thermal-field insulation for high-end manufacturing, quartz consumables for photovoltaic and semiconductor production, and carbon fiber felt materials for flow battery electrodes.
