RULON ® 1439 ® 1439Rulon® 1439 is a white FDA compliantmaterial that is suitable for immersedservice with better wear characteristics thanmost other PTFE compounds. Its color makesit aesthetically pleasing for food andpharmaceutical applications./This material is also resistant to many harshchemicals found in the applicationenvironments where it is typically used. It iscompatible with most commerciallyavailable lubricants for additional reductionin friction.Its properties allow it to be effectivelyutilized as a bearing or sliding surface.Design CriteriaRulon 1439Temperature - Typical Range ˚F (˚C)Maximum PV (continuous)(MPa•m/s)Maximum P - psi (static)(MPa)Maximum V -SFM (no load)(m/s)Shaft Hardness - MinimumShaft finish recommended Ra (µ”/µm)Shaft MaterialEngineering InformationFriction - static & dynamicFlammability ASTM D635Chemical ResistancePhysical DataElongation ASTM D638Tensile Strength ASTM D638(MPa)Specific Gravity-400/+550 (-240/288)10,000 (0.35)*1,000 (6.9)*400 (2)*Rb258 - 16 (0.2-0.4)*Stainless toHardened Steel.15 - .25Non-FlammableGood190%1875 psi (12.9)*2.60A more complete data sheet is available upon request.*Metric measurements in parenthesesTypical Productand Application DescriptionProducts• Automatically moldedbearings & components• Sleeve, flanged andthrust bearings• Piston Rings• Stamped and formedseals• Extruded shapes• Machined parts• Molded shapesApplications• Transmissions• Air Compressors• Appliances• Pillow Blocks• Linear slides• Fluid transfer systems• Vacuum Pumps• Valves• Food ProcessingEquipment18
