Klinger Thermoseal soft-chem® PTFE Gasketing
Categories:	Polymer; Thermoplastic; Fluoropolymer; Polytetrafluoroethylene (PTFE)
Material Notes:	Thermoseal® soft-chem® expanded PTFE sealing material provides excellent corrosion resistance and impermeability along with superior creep resistance and sealability for use in all types of applications. The material's high compressibility enables it to deform under load and conform to irregularities in flange faces for a tight seal with low, minimum sealing stress. Standardizing with it also helps to reduce maintenance, simplify inventory, and save money. Can be used with more fragile piping systems Ideal for boiler applications because it's largely unaffected by steam or condensate for longer life and trouble-free sealing BAM approval for gaseous oxygen Indefinite self life FDA compliant Information provided by Thermoseal Inc.
