TECACOMP® TC
Thermally conductive plastics
Innovative cooling solutions
More than just one option
Plastics have always been considered more as
insulators, while metals are seen as better
conductors of heat. However, in applications
involving natural convection, thermally conducting plastics have been proven to offer
cooling performance comparable to that of
metals. This makes them a true alternative or
an ideal way of supplementing conventional
solutions. A new type of thermally conductive
plastics come into their own in applications
where metals have distinct drawbacks.
Their free formability allows cooling structures to be configured to provide precisely
the required heat distribution. Materials
which also provide electrical insulating
properties can help to reduce the need for
TIMS (thermal interface materials). The
result: fewer disruptive heat transfers and
even more efficient cooling.
Thermally conductive and free forming
Definitely a cool solution: TECACOMP® TC
Depending on the fillers used, components
made of TECACOMP® TC provide thermal
conductivity of between 1 and 25 W/(m K).
This makes them ideally suited for applications such as heat dissipation in electronic
components.

Formability superior to any metal
Thermally conductive plastics from Ensinger
can be freely formed by injection moulding.
This opens up a whole new degree of creative
freedom for the design of effective cooling
elements or insert moulding of complete
assemblies with a sturdy, heat-dissipating
enclosure.
Cost benefits due to broad functionality
Another advantage over using metal is the
facility to equip TECACOMP ® TC plastics
with electrically insulating properties. In this
way, a single plastic component can be used
to cool several different electronic components. Insert moulding of assemblies allows
several functions to be performed in one:
•Mechanical fixture
•Protection against environmental
influences
•Electrical insulation
•Heat dissipation

Added fillers determine the properties
A wide selection of basic polymers such as PA,
PBT, PP, PPS, PEEK and others can demonstrate different thermal conductivity properties
by the addition of specific fillers. Depending on
the filler used, these can be either electrically
insulating or conductive.
By using innovative fillers, the degree of filling
can be relatively minimized depending on the
application. This allows any influence on the
properties of the basic polymers used to be kept
to a minimum.
Electrically insulating
An electrically insulating thermally conductive
plastic is produced by adding ceramic or mineral fillers to the polymer matrix. Ensinger uses
fillers which permit good thermal conductivity
as well as good processability for injection
moulding. Depending on the filler geometry
and degree of filling, thermal conductivity of up
to 10 W/(m·K) can be achieved. A particular effect of these materials is that of minimal tool
wear during machining.

Electrically conductive
By adding graphite or carbon fibres, it is possible to produce thermally conductive materials
which also have electrical conduction properties. Depending on the degree of filling, values
of up to around 25 W/(m·K) can be achieved.
The optimum material selection for your application
Dynamic development
The field of thermally conductive plastics is
currently undergoing a highly dynamic development process. With their indisputable material benefits, plastics are gaining a foothold in
ever wider fields of application. But the range
of different applications is widespread, and
imposes highly specific demands on the materials used. This is why Ensinger develops individual thermally conductive plastics in close
co-operation with customers.
