FAQ: Thermally Conductive TPE 

The demand for thermally conductive plastics is growing. In view of current and future demand, KRAIBURG TPE is preparing and calling on customers and partners to form development alliances of thermally conductive plastics. The focus is on the development of solutions and components made of thermoplastic elastomers (TPE) for the automotive and industrial markets. The goal: intelligent heat management paired with electrical insulation! 

In the following, experts from KRAIBURG TPE answer some of the most frequently asked questions about Thermally Conductive TPE:
 

Are different hardness settings of the material possible?
KRAIBURG TPE has conducted successful initial trials with external partners. Both harder and softer materials can be used.

What method is used to measure the thermal conductivity?
Using the laserflash method according to ISO 18755, the thermal conductivity of the material was measured. The anisotropy of the material provides different measured values in different directions. The X and Y values were determined parallel to the flow direction, while the Z value was determined perpendicular to the flow direction. 

Can the material be listed according to UL94?
Tests conducted have confirmed that UL94 HB listing is possible if required. 

Are there any restrictions in terms of temperature resistance?
There are no particular restrictions as the level is comparable to standard TPS materials. Ultimately, however, it always depends on the application as well as the associated, specific conditions.
