Teflon® is a registered trademark of The Chemours Company (formerly DuPont). The Teflon® name is most commonly used when referring to PTFE (Polytetrafluoroethylene) but the Teflon® brand name is also applied to other Fluoropolymers including FEP (Perfluoroethylene Propylene) and PFA (Perfluoroalkoxy).
Other manufacturers of PTFE resins and their trademarks are:
– FLUON® is a registered trademark of AGC Ltd.
– DYNEON® is a registered trademark of 3M.
– POLYFLON® is a registered trademark of Daikin Industries, Ltd.
– ALGOFLON® is a registered trademark of Solvay, Ltd
Polytetrafluoroethylene (PTFE) is a high molecular weight polymer, one of the most versatile plastic materials known and useful for a large range of products in the high-tech market sector. PTFE can be used in a temperature range from -200°C (-328ºF) to +260°C (500ºF).
Some outstanding characteristics of PTFE include:
PTFE (Polytetrafluoroethylene) is more than a non-stick coating on cookware. It’s grown into a worldwide staple of industrial applications. And for good reason. With great temperature range, chemical and corrosion resistance, and excellent electrical, non-stick and anti-microbial properties, PTFE products have the ability to be formed into many different components. Wherever there’s a need for moving, vibrating or rotating parts, our reputably sourced PTFE will improve your production process by reducing friction, wear, and energy consumption in many types of machinery.
Industry applications include:
Grades of PTFE, each with unique properties and uses.
Standard stock grades include:
Custom grades of PTFE include:
. Glass Fiber-filled PTFE from 5% up to 30%
Milled glass fibers have the least effect on chemical and electrical properties and add greatly to the mechanical properties of unfilled PTFE. The addition of glass improves compressive properties by as much as 40% and improves wear resistance greatly. These compounds resist acids and oxidation but can be attacked by alkalis.
. Graphite filled PTFE from 5% up to 25%
Graphite offers improved chemical resistance to corrosive environments and exhibits good initial wear and rubbing/sliding characteristics in dry and water applications. Graphite is commonly blended with carbon and PTFE.
. Carbon filled PTFE from 5% up to 25%
Carbon has good chemical resistance to corrosive environments. It exhibits good initial wear and rubbing or sliding contact characteristics, both dry and water applications. It is frequently used in piston rings to reduce cylinder wall wear by entrapping abrasive foreign particles in their relatively soft surfaces.
. 15% Carbon Fiber
Carbon Fiber lowers creep and increases flex and compressive modulus. It raises hardness properties and exhibits wear characteristics in water applications. It is often the best choice in automotive applications such as shock absorbers and water pumps. It is an excellent material for use in piston rings, bearings, and thrust washers. A 15% fill is typically called out in certain AMS specifications, however, customer-specific fill percentages are available upon request.
. 5% Molybdenum Disulfide-filled PTFE
This filler is used frequently in combination with others to increase surface hardness, stiffness, and to reduce the starting coefficient of friction and steady-state wear. Its effect on electrical and chemical properties is negligible.
. Bronze-filled PTFE 25% up to 60%
This filler has better wear, creep resistance, and higher thermal conductivity than glass fiber with PTFE. The compound is easily machined but has poor chemical resistance in the presence of acids and alkali. Useful in applications which undergo high mechanical loads or high-speed rubbing contacts where the bronze filler supplies the strength and conductivity to carry away excess, unwanted heat.
Often, two or more fillers will be combined to provide very specific PTFE characteristics.
These are some common blends available in molded PTFE shapes:
