The Expanded Thermoplastic Polyurethane, in short E-TPU, is manufactured by foaming TPU granules, which is similar to EPP foaming process that the TPU granules are also pretreated with high pressure and heat.
With specialized foam mouding machinery and facility, the E-TPU cell foams can be moulded into different shapes. The most advantage and benefit of the Expanded TPU cell foam in shoe sole is as below:
