PTFE Products
When elastomers can’t take the chemistry or the heat, we turn to PTFE. We compression-mold and machine custom PTFE O-rings, gaskets, diaphragms and parts — in food, medical and high-purity grades — to your exact print.
Overview
Where elastomers reach their limit
ARC manufactures custom PTFE components for applications demanding near-universal chemical resistance, wide temperature capability and the lowest coefficient of friction available in a sealing material. We produce PTFE O-rings, gaskets and seals, diaphragms and fully custom molded products using compression molding of PTFE powders, plus coating, dispersion spraying/dipping and fiber processes. Food-grade, medical-grade and high-purity grades support regulated and clean applications. Every part is made to spec — never a stock catalog item — with the engineering support to match grade and geometry to your service conditions.

Custom PTFE Products, Engineered and Made in USA
Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene with an exceptionally broad range of applications. The most widely known brand name for PTFE-based compositions is Teflon by Chemours, a spin-off from DuPont, which originally discovered the compound in 1938. American Rubber Corp is an engineering-led, Made in USA manufacturer of an exclusive range of custom PTFE products, each designed to the diverse and demanding requirements of our customers and valued for its durability and precision. Our PTFE line includes PTFE O-rings, PTFE gaskets and seals, PTFE diaphragms, and custom PTFE molded products, all built to your specification and to your print.
Properties of PTFE
PTFE combines a set of properties that give it high commercial value across industrial applications: outstanding chemical inertness and resistance to aggressive media, a very low coefficient of friction, excellent electrical insulation, a wide operating temperature range, and strong resistance to weathering and aging. These characteristics make PTFE the material of choice where other elastomers cannot survive the chemical or thermal environment.
Fabrication of PTFE Products
Fabricating PTFE products requires specialized processing because the material does not flow readily, even above its melting point. Molded parts are produced by compressing and heating fine PTFE powders blended with volatile lubricants. Metallic surfaces can be sprayed or dipped with aqueous dispersions of PTFE particles to form a permanent coating, and dispersions can also be spun into fibers. Our engineers apply the appropriate PTFE fabrication method for each part to deliver consistent, made-to-spec results.
