When the expandable graphite was treated in a twinkling at high temperature, the form of flake has turned into that of worm, and it can expand from **0 to **0 times. This expandable graphite still retains the characteristics of natural graphite, and also has good expandability, losse and porus. Its temperature rating under the oxygen free is between***0 to ***0 centigrade degree, and it is chemically stable under high temperatures, pressure or radiation. It is widely used in the dynamic and static seals in petroleum, chemical industry, electricity, astronomy, automobile, ship along with many other apparatus`. In order to satisfy the market needs, we have developed Ultra Low Sulfur Expandable Graphite in recent years.
