Product Description

The Expandable Graphite still retains the characteristics of natural flake graphite, and also has good expandability, loose and porous. Its heat-resistant range under the oxygen-free environment is between ***0 to ***0℃, and it is chemically stable under high temperature, pressure or radiation. When the Expandable Graphite was treated in a twinkling at high temperature, the form of flake is turned into that of worm, and the volume can expand from **0 to **0 times. It is widely used in the dynamic and static seals in petroleum industry, chemical industry, electric industry, space industry, and automobile industry, etc. In order to satisfy the market needs, we have developed Ultra Low Sulfur Expandable Graphite in recent years. Simple technology parameter: Fixed carbon: *0%**9.9% Volatile: ≤*0% Expansion Ratio: ******0 Sulfuric acid content: ≤0.*3% PH Value: **7 Moisture: ≤1.0% Screen Oversize: ≥*0% The above technical indexes can be adjusted according to the user’s different requirements.
