Vespel - Polyimide
Vespel is a high-performance polyimide resin. Vespel performs well with or without lubrication under conditions which
would destroy other plastics or severely wear many metals. Vespel parts function over a wide range of temperatures and stresses.
Vespel retains its outstanding creep, abrasion resistance, and strength
under adverse conditions.
Since Vespel does not soften and is thermally resistant, it can carry loads
at temperatures beyond the reach of most plastic materials and
do so while exhibiting extremely low creep.
Vespel polyimide is available in these five resin compositions
to provide a range of property combinations.
| SP-1 |
- Unfilled which provides physical properties and best electrical
and thermal insulation. |
| SP-21 |
- 15% graphite filled which provides low wear and friction for
bearings, thrust washers, and dynamic seals. |
| SP-22 |
- 40% graphite filled which provides improved dimensional stability
and has the lowest coefficient of thermal expansion. |
| SP-211 |
- 15% graphite/10% filled, has the lowest coefficient of friction
over wide range of operating conditions. Lowest wear rate up to
300 degrees F. |
| SP-3 |
- 15% molybdenum disulfide filled to provide lubrication for seals
and bearing in vacuum or dry environments. |
