Advantages and Usage:
The product can be woven into different expandable graphite packing using special process technique. It is suitable for use in sealing at different media, temperature and pressure. In addition, corrosion inhibitor can be added to graphite yarn to produce seal assembly according to extremely corrosive environment and users’ requirements, so that it has more perfect performance.
