In order to manufacture different kinds of reinforced Expanded (flexible) graphite yarns to be used for making different kinds of braided expanded graphite packing, we use expanded 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 braided packing made of these expanded graphite yarns reinforced with different kinds of fibers and circumstance, temperature and pressure. Furthermore, for using these products under severely corrosive circumstance upon the demands of customes, inhibitors of corrosion can be added into the graphite yarns for making the properties of the graphite sealing parts more perfect.
