M&P can make custom Polyimide Machined Parts to your specifications or drawings.
We have a plastic machine shop; Polyimide is one of the plastics we can use to make parts.
MATERIAL DESCRIPTION
Vespel® is a high performance Polyimide material which is formed from resin manufactured solely by DuPont.
Polyimide materials are characterized by a ring-shaped molecular structure containing Nitrogen.
Vespel® will not melt and can operate continuously from cryogenic temperatures to 550°F (288°C), with excursions to 900°F (482°C).
Polyimide machined parts consistently exhibit superior performance in a variety of applications requiring low wear and long life in severe environments
NOTABLE MATERIAL FEATURES
- Excellent temperature resistance
- High wear resistance (especially SP-21)
- Dimensional stable
- Resistant to radiation
- Extremely low out gassing
- Relatively easy to machine
GRADES OF VESPEL®
Vespel® SP-1
Vespel SP-1 is the unfilled base resin grade.
Vespel® SP-1 provides maximum physical strength, elongation, and toughness, as well as the best electrical and thermal insulation values.
Typical applications include spacers, high-temp fixtures, valve seats, balls, gaskets, insulators, and seals.
Vespel® SP-21
Vespel SP-21 has 15% graphite by weight added to the base resin.
Vespel® SP-21 has increased wear resistance and reduced friction in applications such as bearings, thrust washers, bushings, seal rings, slide blocks, and other wear applications.
Has the highest mechanical properties of the graphite filled grades.
Vespel® SP-22
Has 40% graphite by weight.
Vespel® SP-22 has enhanced wear resistance, lower friction, improved dimensional stability (low coefficient of thermal expansion), and improved stability against oxidation.
Typical uses are the same as those for Vespel® SP-21.
Vespel® SP-211
Vespel® SP-21 has 10% PTFE and 15% graphite by weight added to the base resin for the lowest coefficient of friction over a wide range of operating conditions.
It also has excellent wear resistance up to 300°F (149°C).
Typical applications include sliding bearings, linear bearings, and many wear and friction uses listed above.
Vespel® SP-3
Vespel® SP-3 is 15% molybdenum disulfide solid lubricant filled for wear and friction resistance in vacuum and other moisture-free environments where graphite actually becomes abrasive.
Typical applications include seals, bushings, bearings, gears, and other wear surfaces in outer space, ultra-high vacuum and dry gas applications.
POLYIMIDE PARTS
M&P makes Polyimide Machined Parts in a completely controlled environment.
Some Examples of parts Polyimide:
Polyimide O-rings, Polyimide Seats, Polyimide Bushings, Polyimide Bearings, Polyimide Guide Blocks, Polyimide Wear Pads, Polyimide Washers.
