Although Carbon Fiber is predominantly produced from polyacrylonitrile (PAN) and pitch, there is an increasing necessity for alternative, low cost and renewable precursors. Harper has the unique ability to adapt our technology to process nontraditional precursors throughout the entire thermal process. By using nontraditional precursors such as lignin, rayon, polyethylene, and blends, customers have the ability to lower their operating costs and reduce the residence time in the oven
