The PTFE (polytetrafluoroethylene) is a polymer, one of the most versatile plastics known to man. The 3R810 sheet can handle virtually all chemicals in the 0-14 pH range with the exception of molten alkali metals and elemental fluorine. The 3R810 is recommended for applications in the industrial and process industries. It is more economical than the virgin PTFE.
This PTFE sheet can be used for industrial processes and is recommended for sealing joints where chemical products are present.
