TECASINT™ 2000 series can operate up to 536° F continuously.
- Excellent long-term thermal stability
- Outstanding bearing and wear properties
At elevated temperatures, TECASINT™ 2000 formulations offer superior wear rates.
- Excellent creep resistance
- High strength and stiffness properties
- High purity characteristics
Only extremely low levels of extractables and ionic impurities are apparent in TECASINT™ 2011.
- Good chemical resistance
TECASINT™ 2000 series is not attacked by common solvents or fuels and is acceptable for use in contact with many acids.
TECASINT™ 2000 series with their superior physical properties, are ideal for applications in the aerospace, nuclear, automotive, electrical/electronics, and chemical processing industries. TECASINT™ shapes are excellent candidates for high purity applications in the semiconductor processing industry. Typical components produced from TECASINT™ applications 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 TECASINT™ series materials.
