OESH® Shoes, the U.S. footwear brand that makes women’s shoes that are «healthy by design,» has been evaluating how Huntsman’s thermoplastic polyurethane (TPU) materials can be used to create a 100% recyclable shoe sole via 3D printing – with positive results. OESH put Huntsman’s TPU to the test – producing a series of soles using OESH’s unique 3D printing technique, which creates parts directly from pellets. The soles were then recycled into pellets and put back into the 3D manufacturing process. The next step was to test the new recycled sole against those made from virgin materials. Results showed that the recycled sole had the same functionality as the original sole – with no drop-in performance properties. Further information
