For more than ten years, it has devoted itself to the research and development of coal tar pitch spinning process and developed the large-scale production technology of general-purpose pitch based carbon fiber with independent intellectual property rights. The technology adopts two production processes of melt spinning and melt blowing, and the product index performance is stable and high-quality. The carbon content is not less than 95%, the strength can reach 500-1000mpa, the modulus is 30-50gpa, and the ash content is less than 200ppm. The asphalt based carbon fiber felt prepared by melt spraying process has uniform gram weight, high flatness, width up to 1.2m, 1.5m, 1.6m and other specifications! It is widely used in carbon carbon composite materials, civil carbon brake pads, automobile bumpers, carbon paper and other fields, especially in the photovoltaic industry. It plays a very important role in the market of silicon material furnace thermal field insulation parts, and is one of the important raw materials of domestic thermal field insulation products.

Lean production, quality first, committed to providing customers with high-quality products and services!
