Thermal Conductive Compounds for injection moulding

Heat conducting plastics combine the formability of plastics with the thermal conductivity of ceramic, metallic and organic materials. During forming operations – like injection moulding – multifunctional radiator and heating elements as for example cases, coils and heat sinks with mechanic function can be produced, working as heat supply and removal as well. Using injection moulded parts for the heating management of complex assemblies includes the directed heat conduction, the quick heat dissipation and short-time heat accumulation.

Operating characteristics, i.e. the potential of heating management are especially subject to the used starting materials (plastics matrix, kind of filling material, filling form, filling factor and additives), to moulding and tool geometry (part thickness, flow path length, approach and connection geometry) and to the manufacturing conditions (process parameters). Increased thermal conductivity and the interaction between the fillers lead to modifying flow and cooling-down characteristics during processing which have to be taken into consideration regarding design of moulding and tools.

Knowing the specific material data, processing and application behaviour can be described with numerical methods and modern simulator programs. Resulting information are useful particularly for the designer and design engineer in order to permit a quick potential analysis and the design of mouldings which are complex as well.
