EVA Supercritical Foaming Press Machine for shoe

Usage: This kind of Rubber and Plastic Foaming Machine is a specialized foaming machine made according to the supercritical process of polymer materials. We also have noraml EVA Foaming Machine and Secondary EVA Foaming Machine for your choice.

There are currently four main types of raw materials for supercritical foaming: EVA、TPU、TPEE、PEBA。

EVA (ethylene vinyl acetate) is the earliest, most mature, and widely used foam shoe material. Its various properties are relatively ordinary, but its durability index is relatively backward. After long-term wear, it is easy to be "flattened", thereby reducing rebound and cushioning performance.

TPU (thermoplastic polyurethane) has excellent rebound performance and strong durability, but it is relatively heavy and will generate heat after long-term pressure deformation. TPU is divided into aromatic and aliphatic types. Overall, aliphatic compounds have better performance than aromatic compounds.

TPEE (thermoplastic polyester) can be regarded as an upgraded version of TPU, with little difference in rebound, durability and other indicators compared to TPU, but significant improvement in lightweight indicators.

PEBA (polyether block amide), also known as nylon elastomer, has the highest level of resilience, lightweight performance, and durability performance compared to TPU and TPEE, making it a standard midsole for top sports shoes. PEBA has a high cost, and it is common to use PEBA mixed with EVA, TPU and other materials for foaming to reduce costs.
