General:
Shielding Express thermally conductive gasketing
materials use a specially formulated non-toxic
composite consisting of a silicone binder, rubber,
and reinforcing material filled with boron nitride
to achieve high thermal conductivity with excellent
electrical isolation characteristics. This product
can be used in place of various grease compounds,
currently on the market, that contain conductive
particles such as: Beryllia, Alumina, and Mica.
These pads are
extremely flexible and conform readily to mating
surfaces with flatness of ± .003 in. When
reinforced with a glass-fiber cloth, they are
extremely rugged and can withstand considerable
abuse during installation and final torque down.
Gasket pads are cut
to various configurations and can be supplied with
Pressure Sensitive Adhesive (PSA) on one or two
surfaces. The information in the Selection Guide
below identifies 3 popular thermal pad products.
However, many configurations and variations of
these specifications are available.
