PTFE SHEET ROD TUBE TAPE
PTFE Sheet, Rods, Tube, Tape ，are all made by high molecular compound of teflon. They are excellent in chemical stability,corrosion resistant,lubrication ,electric insulation ,antiaging and also it has low friction coefficient. It is widely used in many fields.It can be function in temperature from +260℃-180℃ Few chemical materials except fusing NA and liquid fluorine can affect it.It is called King of plastics.

Name: ss003
Sort: expanded graphite sheets
EXPANDED GRAPHITE ROLLING (SHEETS)
Natural graphite flake is chemically treated to form Graphite
Intercalation Compound. This intercalation compound is then rapidly heated to decomposition. The result is a rapid expansion of the particle size. The bulk density of the worm-like graphite powders is about 0.003g/cc. Then they are formed into graphite sheets by rolling.
Principal applications:
·Glands
·Gaskets used in flanges, covers of observation holes, level meters.
·Direct attach to the metal surfaces for gas phase sealing effectively.
·Especially the expanded graphite rolls can be used as a material for automatic producing lines.
