The materials are used, for example, in the manufacture of bobbins for electric motors. The material can be further strengthened by the addition of mineral fillers, which play an important role. With the right filler, the thermal conductivity of modified plastics can be increased many times over that of unfilled polymers. Szparagowski and his team have developed a range of material types that enable Freudenberg to meet specific customer requirements with tailor-made solutions.
With a blend of physical attributes, including electrical, thermal, and material properties, such as elongation and tensile strength, the TCEI materials exhibit superior thermal conductivity and improved electrical insulation properties compared to commercially available materials. The higher filler content results in a stiffer material that can be molded into thinner cross-sections, resulting in lower material consumption at the same time. The slimmer design of the bobbins provides more space for the copper wire, which can increase motor performance. Bobbins also protect the windings from damage and vibration during assembly and operation.
