In order to manufacture different kinds of reinforced flexible graphite yarns to be used for making different kinds flexible graphite packings, we use flexible graphite as basic material, mixing with natural fiber,synthetic fiber,metal alloy wire (respectively) and proper binding agent,then through specially designed technological process. The packing made of these flexible graphite yarns reinforced by different kinds of fibers and metal alloy wires, are suitable for sealing under different media, circumstance, temperature and pressure.

It is twisted from carbon fiber yarns and used as heat insulation materials in thermal installations and heat conducting systems. Also can be extensively made to all kinds of carbon fiber textiles; and an excellent substitute for asbestos.
