MuCell lightweight energy absorbing foams

Trexel MuCell microcellular foaming technology is used in combination with injection moulding to produce lightweight and durable shoe midsoles. It involves the injection of a supercritical fluid (SCF), typically nitrogen or carbon dioxide, into the molten plastic during the moulding process. This creates a microcellular foam structure within the plastic part, resulting in various benefits such as weight reduction, polymer reduction, reduced warpage and faster cycle times. The sole is moulded directly onto the fabric, finishing the shoe in a single step.
