Flexible Graphite Yarn
※ In order to manufacture different kinds of reinforced flexible graphite yarns to be used for making different kinds flexible graphited packings, we use flexible graphited as basic material, mixing with natural fiber, metal alloy wire (respectively) and proper binding agent, then through specially designed technological process. The packing made of these flexible yarns reinforced by different media, circumstance, temperature and pressure. Furthermore, for using these products under severely corrosion can be added into the graphited yarns for making the properties of the graphite sealing parts more perfect.
