Sintimid V
SINTIMID V with its superior physical properties, is ideal for applications in the aerospace, nuclear, automo-
tive, electrical/electronics, and chemical processing industries. SINTIMID V is an excellent candidate for high
purity applications in the semiconductor processing industry. Typical components produced from SINTIMID V
include seals, thrust washers, bushings and wear pads in transportation/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 SINTIMID V.

SINTIMID

V polyimide
stock shapes provide
a superior combination
of high temperature
and bearing and wear,
properties that make it
an ideal choice for the
most demanding appli-
cations. SINTIMID V
is characterized by
its long-term thermal
stability, outstanding
wear resistance, high
creep resistance, and
strength up to its
continuous use
temperature of 572° F.
Specialty grades
containing internal
lubricants such as
PTFE and graphite
are available for
applications requiring
improved wear
resistance and lower
coefficients of friction. Superior high temperature characteristics
SINTIMID V can operate up to 572° F continuously. Excellent long-term thermal stability Outstanding bearing and wear properties
At elevated temperatures, SINTIMID V formulations offer superior wear rates. Excellent creep resistance High strength and stiffness properties
SINTIMID V has a tensile strength of 20,000 psi at room temperature. High purity characteristics
Only extremely low levels of extractables and ionic impurities are apparent
in SINTIMID V. Good chemical resistance
SINTIMID V is not attacked by common solvents or fuels and is acceptable for
use in contact with many acids. TYPICAL PROPERTY VALUES
