Polyimide
--
When compared to most other organic or
polymeric materials, polyimides exhibit
an exceptional combination of thermal
stability (>500°C), mechanical
toughness and chemical resistance. In
addition, they have excellent dielectric
properties.
Uses -
Used a lot in wear applications, machined
gears, bushings and bearings, aerospace
and aircraft parts, ring seals, thrust washers,
wear strips. Also, because of their high
degree of ductility and inherently low CTE,
polyimides can be readily implemented into
a variety of microelectronic applications.
Multilayer thin and thick film applications
on large silicon or ceramic substrates can
be readily achieved.
