Ensinger Sintimid™ V-HPHT high purity high temp Polyimide (PI) (discontinued **)
Categories:	Polymer; Thermoplastic; Polyimide, Thermoplastic
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. Specialty grades containing internal lubricants such as PTFE and graphite are available for applications requiring improved wear resistance and lower coefficients of friction. Superior high temperature characteristics Excellent long-term thermal stability Outstanding bearing and wear properties (at elevated temperatures, SINTIMID™ V formulations offer superior wear rates) Excellent creep resistance High 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.
