Thermally conductive LUVOCOM® compounds
Plastics are poor heat conductors. The thermal conductivity in standard materials lies between 0.1 and 0.4 W/mK. By using special additives – generally mineral-based – LUVOCOM® materials from this product group achieve significantly higher values of up to more than 40 W/mK.
Through our special expertise in compounding, we provide you with precisely the material you need to meet your requirements. Electrically conductive and electrically insulating products are also available.
Up to 200 times higher thermal conductivity with
Thermal conductivity in W/mK, measured by the hot disc method:
In great demand in many industries
Wherever it is necessary to avoid overheating, thermally conductive materials are in demand. In the electrical and electronics industries, the heat dissipation from casings used for coils or housings for hard discs and other mass data storage devices can be increased through the use of thermally conductive LUVOCOM® materials. Yet the shape remains very flexible: during injection moulding cooling fin structures can be achieved to allow the complete enclosure of even geometrically complex components.
In mechanical engineering, thermally conductive LUVOCOM® materials are suitable for friction bearings and motor housings. And there are also numerous applications in the automotive industry.
Thermally conductive plastics cause LEDs to shine
All over the world the use of lighting systems with LED (light emitting diodes) technology is on the increase. They can be found in applications such as automobiles and living areas. With the requirements of LED lamp manufacturers particularly in mind, Lehmann&Voss&Co. has developed new thermally conductive plastics, which are used here as heat sinks and enclosures.
The materials are characterized by a specially adjusted thermal conductivity ranging from 0.6 to 1.5 W/mK, good strength figures, electrical insulation, a white coloration and optional flame retardation, tested to UL94 V0. PET, PA 6 and PC are the base polymers. Thanks to the customized properties of the materials, the lamps achieve a higher performance and service life, while the good processing characteristics permit freedom in design and allow cost savings compared with other materials such as metals and ceramics.
