- Polymer Name:Polytetrafluoroethylene (PTFE)
VALFLON® F 391 is a PTFE-based formulation that is particularly suitable for the manufacture of a wide range of component parts, such as valve seats and balls, packed sealing elements (V-rings), bushings and washers. It can also be produced in tapes of different widths and thicknesses for the coating of sliding surfaces and finishing of cooking tops. VALFLON® F 391 features excellent workability and is economically advantageous in the manufacture of parts machined on automatic lathes by large quantities.
