The new thermally conductive polyamides from LANXESS are making a big impression in their first applications. For example, the modular flange for a drive used in car interior ventilation systems is made from the recently launched polyamide 6 Durethan BTC 75 H3.0 EF. The thermoplastic, which is reinforced with a 75 percent mineral content, is replacing a polyamide with a glass fiber/mineral mix for thermal conductivity. “Compared to conceivable alternative materials, our compound conducts heat better and is the most cost-effective solution. It performs best in terms of mechanical properties, resistance to thermal aging and flowability and, thanks to its electrically neutral stabilization, helps prevent contact corrosion,” explains Stefan Theiler, an expert in highly filled polyamides at LANXESS. Robert Bosch GmbH is using the flange made with this material in a fan module that is being incorporated into the cooling system fitted inside the passenger compartments of several international automakers. SFS intec GmbH, which is based in Korneuburg, Lower Austria, is manufacturing the flange.
