Right: LED lighting was one of the first high volume target markets for thermally conductive plastics


to be many solutions covering all of these aspects, but there is a lot of potential to create optimally customised solutions for specific applications.” The company has developed a number of heat conducting mineral additive products to meet some of these challenging applications, according to Angelina Schöffel, Customer Support & Marketing. These include modified graphite grades – marketed as GraphTHERM and GraphCOND – which can improve thermal and electrical properties in plastics and coatings applications. GraphTHERM is optimised for the highest level of thermal conductivity, while GraphCOND is designed for good thermal conductive performance at low filling rates. Graphene nanoplatelets have been developed as a high-end material for specific applications. These materials enhance high thermal and electrical conductivity in combination, while mechanical properties such as strength and surface resilience can also be improved. And MagTHERM is a white mineral additive that improves thermal conductivity while maintaining electrical insulation.

Ready-to-use solutions According to HPF The Mineral Engineers, a division of Quarzwerke, there have been ongoing material developments in the thermally conductive compounds arena for more than a decade. However, these ready-to-use solutions did not make an appearance on the market. “The reason was quite simple. There were no reasonable applications to use a thermally conductive material, except for those that were electrically conductive at the same time,” says Péter Sebö, Head of Marketing & Market Development. “End-users and OEMs now realise the value of

such compounds and are engaged in looking at and considering thermally conductive materials in more detail, in terms of changing the design or construction of a part that needs


replacing or completely re- developed,” he says. “Over the past two years, the market has moved noticeably towards thermally conductive compounds for a number of reasons.


These include an increasing number of applications, while the fear of using thermally conductive plastics instead of metals is now decreasing. In addition, a wide


range of grades is now available worldwide, and the know-how of different companies within the supply chain is increasing, which gives much needed security and guarantees.”


E-mobility demands E-mobility is currently one of the big driving forces in the development of thermally conductive compounds. “In electromobility, the objectives and achievements of future applications are closely linked to the use of new and innovative plastic materials and thermally conductive compounds will play an increasingly important role,” says Sebö. “The number of E&E applications in terms of


automation, communication and security components is steadily increasing in the car of the future, particularly in e-mobility. The issue of heat generation and its effective conduction is a major challenge in many of these applications. In addition, in alternative power drives, battery technology has potential for heat conductive plastics, for example in battery housings and other components, as well as in the still costly and complex battery cooling systems. At the same time, a good choice and combination of plastics and fillers may offer a technical and economic alternative to metal. The resulting weight reduction can help to improve the reach of electrical cars,” Sebö says.


“In addition, new developments in E&E, such as electrical tools, medical devices, lighting applications and tribology, are expanding the role of thermally conductive plastics. The increasing desire for higher levels of integration and downsizing of functional components requires the use of novel plastics for the realisation of highly functional system solutions. Thermally conductive plastics allow the possibility of achieving the required mechanical properties, heat dissipation function and electrical insulation in one automated production step.
