The ETPU machine plays a key role in transforming the way shoe midsoles are made. By using Expanded Thermoplastic Polyurethane (E-TPU) foam, manufacturers can create midsoles that are both lightweight and durable.
The ETPU machine foams TPU granules through a high-pressure process, similar to Expanded Polypropylene (EPP) foaming. This method ensures that the E-TPU foam cells can be molded into the ideal shape for midsole applications. What makes the E-TPU material special is its ability to remain lightweight, making shoes more comfortable and responsive to wear.
