More Performance, More Heat: The Potential of Thermally Conductive TPE

Electrification is transforming virtually every market: electric mobility, power tools, household appliances, and industrial equipment. More and more functions are being electrified, and electronic components are becoming more powerful while also becoming more compact. As a result, the amount of heat generated in an increasingly smaller space is also rising. Efficient thermal management is therefore becoming a critical factor in the development of modern components.

This is where thermally conductive plastics can showcase their unique properties. They enable heat to be dissipated in a targeted manner while simultaneously leveraging the advantages of polymeric materials in terms of processability, design freedom, and functional integration. In particular, electrically insulating yet thermally conductive plastics open up interesting possibilities for applications where heat must be dissipated in a controlled manner without compromising electrical safety.
 

The demands placed on electronic devices are increasing. This is evident in ever-more-powerful smartphones, more compact LED systems, and more powerful power tools that also charge faster. I see similar trends in inquiries regarding industrial applications.

Generated heat must be reliably dissipated from the component or from the temperature-sensitive part. Inadequate thermal management can limit the performance of electronic systems and affect their service life and reliability. The selection of suitable materials therefore becomes relevant early in the component development process.

A particularly interesting property of these plastic solutions is the combination of thermal conductivity and electrical insulation. Unlike electrically conductive materials, they can transport heat while also helping to insulate electrically sensitive areas from one another.

This opens up potential applications, for example, in batteries, charging systems, LEDs, connectors, or drive units. The importance of such material combinations continues to grow, particularly with regard to electromobility and energy technology.

In nearly all applications, thermal conductivity alone is only one part of the list of requirements. Plastics, as well as thermoplastic elastomers offer a high degree of design flexibility. Complex geometries can be produced cost-effectively in high volumes using injection molding. With a well-thought-out design, various functions can be combined into a single component.

This becomes particularly interesting in multi-component solutions. By combining different bonding compounds in one part, it is possible, for example, to achieve hard and soft areas, thermal conductivity, sealing functions, or defined surface properties into a single component.

Another positive aspect of thermally conductive plastics is their often high resistance to corrosive influences. While corrosion resistance in both plastics and metals depends heavily on the specific material and the operating environment, plastics can offer advantages in many applications due to their chemical structure.

With increasing electrification, thermal management will no longer be relevant only for traditional electronic components. Material developers, component designers, and processors must increasingly work together to examine how heat is generated, transferred, and dissipated within complex systems.

We will be focusing on precisely this interplay in our upcoming webinar in collaboration with the LEHVOSS Group. The webinar will center on thermally conductive thermoplastic elastomers, polyamide, and polypropylene materials, their properties, and potential applications. 

Special attention will be given to multi-component injection molding and the question of how heat dissipation, reliable material adhesion, and design freedom can be combined.
