TECASINT™ is a range of non-melting high temperature polyimides characterized by high strength over a wide range of temperatures, good long term thermal stability, minimal thermal expansion and excellent wear resistance among other things. The TECASINT 2000 series offers these enhanced thermal properties along with lower moisture absorption, a higher degree of toughness, and better machining properties. TECASINT 2011 is unfilled, while TECASINT 2021 contains 15% graphite which offer improved wear resistance and a lower coefficient of friction.

• Superior high temperature characteristics
  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

• While TECASINT 2021 contains 15% graphite which offer improved wear resistance and a lower coefficient of friction.
• Tecasint® 2021, Vespel® SP-21, where 15% graphite by weight is added to the base resin for increased wear resistance and reduced friction in applications such as bearings, thrust washes, bushings, seal rings, slide blocks and other wear surfaces. These have the highest mechanical properties of the graphite-filled grades.

TECASINT 2000 series with their superior physical properties, are ideal for application in the aerospace, nuclear, automotive, electrical/electronics, and chemical processing industries. TECASINT shapes are excellent candidates for high purity applications in the semiconductor process industry. Typical components produced from TECASINT applications include seals, thrust washers, bushings and wear pads in transportation and 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.
