In October 2017, for an undisclosed sum, it was announced that Lehigh Technologies had been acquired by Michelin and will operate as a subsiduary of that firm. Lehigh Technologies is a specialty materials company that transforms end-of-life tires and other post-industrial rubber into high-performance, lower cost, sustainable micronized rubber powders (MRP). These MRPs replace oil- and rubber-based feedstocks in a wide range of industrial and consumer applications, including high performance tires, consumer and industrial plastics, consumer goods, coatings & sealants and construction materials. Lehigh tailors its PolyDyne and MicroDyne MRPs to customers needs to maximize benefits and optimize performance. manufactures micron-scale engineered rubber powders for use in a wide range of industrial and consumer applications. Lehigh uses proprietary milling technology to cryogenically grind rubber from end of life tires into an ultra-fine powder; orders of magnitude finer in size than traditional "crumb rubber" or "ground tire rubber." The firm's high quality engineered rubber powder allows manufacturers to formulate the performance characteristics of rubber into their product-lines. In addition to having the capability to manufacture several different particle sizes; the Lehigh Technical Center offers custom technical guidance to formulate with PolyDyne and MicroDyne for, Tire, Coatings, Paints, Sealants, Plastics and Rubber Applications. Employing state of the art manufacturing processes, Lehigh operates a 100 million pound manufacturing facility that is both ISO 9001 and 14001 certified
