Material Notes:
SINTIMID™ V polyimide stock shapes provide a superior combination of high temperature and bearing and wear, properties that make it an idea choice for the most demanding applications. SINTIMID™ V is characterized by its long-term thermal stability, outstanding wear resistance, high creep resistance, and strength up to its continuous use temperature of 572°F.Superior high temperature characteristicsExcellent long-term thermal stabilityOutstanding bearing and wear properties (at elevated temperatures, SINTIMID™ V formulations offer superior wear rates)Excellent creep resistanceHigh strength and stiffness properties (SINTIMID™ V has a tensile strength of 20,000 psi at room temperature)High purity characteristics (only extremely low levels of extractables and ionic impurities are apparent in SINTIMID™ V)Good chemical resistance (SINTIMID™ V is not attacked by common solvents or fuels and is acceptable for use in contact with many acids)SINTIMID™ V with its superior physical properties, is ideal for applications in the aerospace, nuclear, automotive, electrical/electronic, and chemical processing industries. It is an excellent candidate for high purity applications in the semiconductor processing industry. Typical components produced from SINTIMID™ V include seals, thrust washers, bushings and wear pads in transportation/off-highway equipment, insulating and support elements in electrical welding and brazing equipment, and wafer-handling components in the harsh environment of semiconductor plasma ovens. Pump and valve seals, vanes, and piston rings are also commonly produced from SINTIMID™ V.Information Provided by Ensinger Industries, Inc.Sintimid has been replaced with Tecasint in the Ensinger product line.
