Vespel, Engineering Plastics
VESPEL: PI
(Polyimide) is an extreme performance Polyimide that combines the physical
properties of metals, plastics, and ceramics. Typical attributes of Vespel
include; low wear and friction at high PV, outstanding resistance to creep,
superior strength / impact resistance, and continuous operation temperature
of 500 F (260 C) with short-term excursion capability to 900 F (482 C).
Vespel is available in many grades to meet specific design requirements.
The current available grades include; SP-1 (unfilled), SP-21 (15% graphite),
SP-22 (40% graphite), SP-211 (15% graphite and 10% PTFE), and SP-3 (15%
molybdenum disulfide) Vespel components are commonly found in valve seats,
wear plates, thrust washers, and semi-conductor manufacturing equipment.
