M&P can make custom Vespel Machined Parts to your specifications or drawings.

We have a plastic machine shop; Vespel® 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 only 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).
Vespel® 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.
Vespel® SP-21 has the highest mechanical properties of the graphite filled grades.

Vespel® SP-22

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.

VESPEL MACHINED PARTS

Vespel® Machined Parts are made in a completely controlled environment.

Some Examples of parts we can machine from Vespel®:

Vespel O-rings, Vespel Seats, Vespel Bushings, Vespel Bearings, Vespel Guide Blocks, Vespel Wear Pads, Vespel Washers.
