PTFE can be used in a temperature range from -350F to +500F. Prices of PTFE are stable, worldwide. Typical applications include seals, gaskets or structural components where temperature or chemical resistance is essential. With compounding, this range can be extended to -65 and 300F, but rarely operates at both extremes and always as a special compound. China, Russia and India being major producers of PTFE. Due to its low elasticity, PTFE virgin is not suitable with high mechanical loads (cold flow, plastic deformation depending on time (creeping)). This grade comes in sheets, rods and tubes. Both Glass and Bronze filled PTFE experienced lower shrinkage (0.5% over a temperature range of 30-32 degrees Celsius). Physical Properties Color White Material Skived Temp. Virgin Grade PTFE Virgin grade PTFE is made from virgin PTFE resin. PTFE is the most chemically resistant plastic known and is unaffected by most corrosive liquids, vapors, and gases. Durlon Virgin PTFE demonstrates high dielectric strength. Most people commonly utilise PTFE by using a commonly seen trademark: Teflon, which is a PTFE coating for non-stick household items. FDA Approved: PTFE is available in virgin & filled compounds to improve the basic characteristics to match very diverse applications & optimization for specific end users. . Other trade names for PTFE include Fluorosint, Interplast, Rulon, and Semitron ESD. It is also interesting to note that virgin PTFE reached a much lower minimum temperature. PTFE can be used as low as - 436 F (-260 C ). Author: This means that the material is "moving" with thermal changes, which is known as cold flow. 100% pure PTFE, white with hardness 55 D, is resistant to almost all chemicals apart from fluorine, molten alkali metals and halogens. The other interesting feature of PTFE is that while it has an operating temperature range of -400 to +550F, it actual starts to transition at around 78F. The Technical Data Sheet of PTFE & Filled PTFE exhibits mechanical, thermal, electrical and chemical properties of PTFE and Filled PTFE. Impact Strength: 2.00 ft-lbs./in. Temperature Range -200 O C - +260 O C . Ms. Kitty . AF001 Virgin PTFE PTFE is one of the most chemically inert materials known. China Virgin Ptfe Temperature Range Manufacturers, Supply Virgin Ptfe Temperature Range with High Quality, Wholesale Virgin Ptfe Temperature Range with Low Price, High Quality. Recommended for Outdoor Use: YES . +8613804148076. The grade of PTFE is selected from Virgin & Filled PTFE grades of PTFE, based on required property for required service conditions / applications. It is the best known non-stick material with a coefficient friction comparable to wet ice on wet ice. Certain highly fluorinated oils only swell and dissolve PTFE at temperatures close to the crystalline melting point. TYPICAL . Once molded, the material can't be remolded like other thermoplastics, so it acts like a thermoset. FDA Approved: . recycled PTFE processed into skived or molded sheet Durlon Virgin PTFE is made with only pure PTFE resins. The operating temperature of Virgin PTFE (PTFE with no fillers) ranges from -75C to +260C. For example, the virgin PTFE material has a tensile strength of 4075 psi at room temperature (approximately . PTFE is insoluble in all solvents up to temperatures as high as 300 o C ( 572 o F). With PTFE temperature limit being -400 and the maximum temperature at +550, it can maintain structural integrity and perform perfectly at extreme temperatures. Facebook; Contact Now; YouTube; Twitter; English . Polytetrafluoroethylene ( PTFE) is a synthetic fluoropolymer of tetrafluoroethylene that has numerous applications. It also has very good sliding properties. With an operational temperature range between -300 degrees Fahrenheit and +450 degrees Fahrenheit, PTFE may be able to maintain structural integrity and function at extreme temperatures, but performance can still be greatly affected. Certain highly fluorinated oils only swell and dissolve PTFE at temperatures close to the crystalline melting point. Annual worldwide consumption of PTFE is around 1,50,000 tons and expected to grow @ 5% p. a. Tensile Strength: 4,500 psi. PTFE has excellent dielectric properties and provides excellent thermal insulation with an operating temperature range of -400F to 500F. Temperature Range: -350F to +500F. It is one of the most well-known and widely applied PFAS, which in recent years however came under increased scrutiny by academic researchers because of adverse health effects, including cancer. What can I do for you? It has excellent sealability characteristics, cuts easily and separates cleanly from flanges after use. Specifications Met: ASTM D3294, ASTM D3308, Made of FDA Listed Materials, UL 94V0. PTFE is insoluble in all solvents up to temperatures as high as 300 o C ( 572 o F). Used especially for application requiring high purity, non-contamination and exceptional dielectric properties. The standard temperature range for this material is -40F to 250F. It is used in many different applications and industries Extreme chemical resistance & thermal stability Very low coefficient of friction . Virgin Teflon Polytetrafluoroethylene (PTFE) Data Sheet Materials Teflon is a brand name for polytetrafluoroethylene (PTFE), a synthetic fluoropolymer of tetrafluoroethylene that has numerous applications. With rubber compounds, we must always be cognizant of the fluid in contact to ensure chemical compatibility. : Min Max-212C . PTFE mechanical properties are low compared to other advanced engineering plastics, but its properties remain useful over a temperature range of -400 F to 400 F forming its broad operating range suitable for many applications. It was observed that the virgin material experienced the highest shrinkage (0.9% over a temperature range of 40 degrees Celsius). Also, while PTFE temperature range is -400 to +550 degrees Fahrenheit, it begins transitioning at several points, meaning that the PTFE material moves as a result of thermal changes.
