Teflon® gaskets, or more properly gaskets made from PTFE gasket materials, are an ideal choice for applications involving aggressive media. The non-reactive characteristics of PTFE gasket material ensures that gaskets produced from these materials are quite impervious to attack and degradation by hostile gases, vapours, and fluids.

PTFE (polytetrafluoroethylene) is a synthetic fluoropolymer of tetrafluoroethylene that has numerous applications. Teflon® is the best known brand name of PTFE-based formulas. Teflon® is a trademark of E. I. du Pont de Nemours and Company (Dupont), who discovered the compound.

PTFE gasket material combines excellent dielectric properties with a very low coefficient of friction and an ability to service a wide range of operating temperatures, from -400°F to 500°F. The real strength of PTFE gasket material is that is among the most chemically resistant materials known. This ability to resist chemical attack makes PTFE gasket material the compound of choice from which to manufacture gaskets for use in severe service applications.

Gaskets manufactured from PTFE gasket material consisting of 25 per cent glass-filled PTFE skived sheet will service about 85 per cent of all caustic chemical applications in many industries. The remaining 15 per cent of these applications can be serviced by PTFE gaskets produced from restructured or molded sheet – in fact, gaskets produced from this type of PTFE gasket material are likely better suited for Fibreglass Reinforced Plastic (FRP), PVC, and cold flow applications, if manufactured using the expanded version.

Canada Rubber Group Inc. (CRGI) precision fabricates gaskets and other rubber parts and components from PTFE sheet. We stock PTFE sheet in a variety of styles and thicknesses from leading manufacturers such as Teadit North America and Technetics Group. Styles of PTFE gasket material that we stock include the following:

CRGI can supply PTFE gaskets manufactured from any of the above sheets. We can custom manufacture gaskets and parts from prototype and no order is too big or too small – we are equipped to handle mass production runs or small-lot orders equally well, and can provide rapid turnaround on urgent needs or emergency service. To find out how we can service your PTFE gasket needs, contact our sales department today at crg@canadarubbergroup.com.
