Keratherm White
|
Description
|
|
The
highly thermally conductive White
Group with their well balanced thermal and electrical
or
dielectrical
behavior are created by filling a
silicone elastomer base with aluminum oxide. An
increase in
mechanical
strength can be achieved by fiberglass
reinforcement. Both the unreinforced
and reinforced film types can
optionally be supplied with an adhesive
coating. In general, however,
the very good self-adhesion of the film will be
sufficient for the mounting required.
