Wires that enable a sustainable future. Reduce waste Less scrap with our coating process 80 % Where sustainability starts Sustainability starts with more than just building electric motors with higher performance. We believe it begins by taking a more sustainable approach to manufacturing the critical components of those motors—their magnet cores. That's why we're proud to produce greener magnet wire that is eco-friendly and built to last. ​ Sustainability meets PERFORMANCE Did you know that traditional, carbon-based vehicles transportation accounts for about a quarter of all global energy consumption? At Tau, we want to facilitate the transition to electric power, cutting the carbon footprint of transportation by at least two thirds. We believe that sustainability starts not only with the required electric motors with higher performance but already with the greener manufacturing of their magnet core. Sustainability requires thinking OUTSIDE THE BOX Electric motors have been considered a fully developed technology for decades, with little change in wire coating chemistries and thermosetting plastics remaining the standard. Until now. Tau merges these worlds to open up a whole new life of high performance, sustainably. Our R&D simply focuses on what end customers want - whether automotive, energy or consumer goods - and redesigns processes to be state-of-the-art, setting new industry standards for years to come.
