RULONRULON ® ® 488/Rulon® 488 is a dull turquoise materialoriginally developed for use with paintedsurfaces. It has been used in veneer dryerbearings in the plywood industry.Its excellent wear resistance, especially inextremely dry environments, make it amaterial of choice in hydrogen and natural gascompressors. Its almost universal chemicalresistance enables it to withstand corrosivesand acids sometimes present in trace amountsin these environments.It has a higher load capacity than Rulon® J andbetter abrasion resistance than both Rulon® Jand Rulon® 123.Design CriteriaRulon 488Typical Product andApplication DescriptionProducts• Automatically moldedbearings & components• Sleeve, flanged andthrust bearings• Piston Rings• Stamped and formedseals• Extruded shapes• Machined parts• Molded shapesApplications• Pumps• Mixers• Compressors• Appliances• Automotive• Insulators• Linear slides• Pipe support• Wear bandsTemperature - 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 & dynamicWater Absorption ASTM D570Flammability ASTM D635Chemical ResistanceThermal ConductivityBTU/hr/sq. ft./˚F/in.Linear Coefficient ofThermal ExpansionPhysical Data(78˚-200˚F)(26˚ -93˚C)(78˚-300˚F)(26˚-149˚C)Elongation ASTM D638Tensile Strength ASTM D638(MPa)Deformation (1500 psi - 24 hr.
