Product Name: Hot Resistance Virgin Teflon PTFE Sheet/Plate PTFE Sheet Best Service Standard: Standard, Nonstandard Performance: Temperature Temperature: Temperature Mechanical Seal Pressure: High Pressure Mechanical Seals Trademark: RILSON Transport Package: Wooden Cases Origin: China Product Description ed,PURE,Expanded PTFE sheetsPTFE (Teflon )sheet is the mostly consumed category of florin plastics, Which has the lowest coefficient of friction in all the engineering plastics. It has the excellent chemical corrosion-resistance, which is able to endure all kind of chemistry material. And it has rather good electricity-resistance, which is not affected by the temperature and is called" Kingof plastics". PTFE sheets can be divided to five kinds: pure virgin PTFE sheet, expanded PTFE sheet, Moldable PTFE sheets, Skived PTFE Sheets, Modified PTFE SheetExpanded PTFE SheetExpanded PTFE Sheet is ahigh performance sheet gasket material made of multi-directionally expanded virgin PTFE. It is asoft, form-in-place gasket material that conforms to almost any sealing surface. It is capable of withstanding awide range of pressure, temperature and chemical environments. Due to its highly fibrillated microstructure, it has excellent creep resistance compared with other PTFE products.Pure PTFE Property:PropertyUnitPure PTFE ResultTensile strengthMPa≥15.0about 20 ~45Elongation at break%≥150 about 200~ 350Apparent densityg/cm32.1-2.2Dielectric strengthKV/mm>1400Resistance of surface (woring voltage 500v)Ω3.7*106Moldable PTFEsheetsandSkived PTFE SheetsPTFE skived Sheet is manufactured by technique of compacting, sintering, rotary cutting with PTFE granular resin. It has good dielectric performance and non-aging, best anti chemistry corrosion ability and wide applying intension range.PTFE molded sheet is manufactured by molding process with PTFE regular resin and sintering. It is very suitable for seals, lining, diaphragm, spacer guide and bearing pad for bridge.Specification:Itemlength(mm)width(mm)thicknessMolded sheet3003002-1004004002-1004504502-1005005002-1006006002-1008008002-100100010002-100120012002-100150015002-100180012002-50180018002-50200010002-50200020002-50Skived Rolled Sheet/skived tape10-27000.03-10skived sheet10-270010-27000.03-10Note: we could make irregular or not included sizes according to requirement of customersModified PTFE SheetEven if PTFE products have excellent properties, like high/low temperature resistance, chemcial resistance, weathering resistance, dielectric superiority and high lubricity, sometimes we still need to improve its hardness, wear resistance, creep resistance and dimensional stability.Filled PTFE products has more outstanding performance by adding filler such as carbon, graphite, bronze, glass fiber, carbon fiber, MOS2, PEEK, PI, POB BaSO4, SiO2, glass bead, polyamide, etc.Details of PTFE filled with other materials :Filled materialsCommon filled ratio( Quantity %)Main performancesBronze40, 60Increases hardness and wear resistance;Increases dimensional stability and compressive strength;Carbon5, 10, 15Increases compressive strength, hardness, wear, and load properties.Good chemical resistance;Improves electrical properties.Graphite5, 10, 15Improves the deformation under load; Reduces initial wear;Improves thermal and eletrical conductivityGlass Fiber10, 15, 25Increases compressive strength, rigidity and wear.Reduces creep and cold flow; Improve Dimensional Stability.Carbon Fiber10 , 15, 25Increases compressive strength, hardness, wear, and load properties.Reduces creep and cold flowPolyphenyl ester5, 10, 15Improve the lubrication performance;Enhance the mechanical strength;Increase using temperatureBaSO45, 10, 15Increases compressive strength, hardness and wear resistanceReduces creepSiO25, 10, 15Increases hardness and wear resistance; Improve Dimensional Stability.Glass beads5, 10, 15Reduces creep and cold flow;Lower densityIncreases hardness and wear resistance;Others materialsPEEK(polyetheretherketone), PI(Polyimide), MoS2are also okAnyrequest feel free to contact us
