Expanded Graphite Sheet
Category: Graphite Sheet
Product Style Number & Name:
GS1000 Expanded graphite sheet
GS1000 Expanded graphite sheet
Our GS1000 is selected from the high purity natural flake graphite. It is made through the advanced chemical treatment and mechanical procedure without fibers, binders or other additives.
It offers excellent sealing capabilities such as thermal stability, corrosion resistance, aging stability, self-lubricity, compressibility, and elasticity. It can serve for long time even under harsh working conditions with a very low maintenance cost. It is an ideal substitute for asbestos sheet.
Applications:
It is the basic material for making various kinds of reinforced graphite sheets, graphite tapes, packings and sealing gaskets. Widely used in chemical, automotive and pump, valve industries.
