B.I.R.S. Machine & Supply located in Anniston, Alabama can cut High Quality PTFE (Teflon®)Gaskets for
the industrial world.
B.i.R.S. Machine & Supply custom cut virgin, filled or reprocessed PTFE (Teflon®) .010 - 2.000" thick gaskets. We fabricate custom PTFE gaskets by means of stanmping, flash cutting, stamping, punching, CNC Routing, CNC Machining, water jet cutting, and laser cutting. Polytetrafluoroethylene (PTFE) is DuPont's trademark of Teflon®. It is a synthetic fluoropolymer of tetrafluoroethylene consisting completely of carbon and fluorine. It is innately hydrophobic (repelling water and water containing substances) and has one of the lowest coefficients of friction against any solid material. PTFE (Teflon®) has excellent dielectric properties and provides excellent thermal insulation with an operating temperature range of -400°F to 500°F. PTFE is the most chemically resistant plastic known on earth and is unaffected by most corrosive liquids, vapors, and gases.
PTFE (Teflon®) is generally offered in thicknesses spanning from .002" to .250" thick and conforms to both FDA and AMS specifications, making it acceptable to both medical and food production industries. B.I.R.S. Machine can custom manufacture quantities from prototype, short run and through large production runs. We can also machine and fabricate custom PTFE (Teflon®) components to your specifications.
Virgin grade PTFE (Teflon®) gaskets are made from 100% pure material which is used in most general applications. It is whiter in color compared to filled and reprocessed PTFE. It is extremely soft and formable and is often used for chemical resistant seals, gaskets, and lantern rings. manufactured from the resin producer and has never been processed into a shape. PTFE Virgin possesses the highest physical and electrical insulation properties and has increased resistance to creep (compression) under load.
Filled PTFE (Teflon®) gaskets are made from PTFE which integrates additives and fillers in order to improve the performance of the gasket. Fillers improves the gaskets ability to wear and enhances its unique combination of chemical, physical and electrical properties. Filled Teflon® is the most common type of PTFE gasket for industrial use as it exhibits improved mechanical strength compared to Virgin PTFE. Glass, mica, carbon, stainless, ceramic, bronze, and fiber particles are typical fillers that are used to enhance the mechanical strength of the gasket depending on the application. Various amounts 5% - 60% fillers are added to PTFE to increase properties.
