PECOAT® E-TPU Foam Granule
ETPU is the abbreviation of “Expanded Thermoplastic Polyurethane”, which is a foamed thermoplastic polyurethane granule and is a product processed from thermoplastic polyurethane elastomer (TPU). Due to its structure resembling popcorn, people also call it ” TPU Popcorn ” .
ETPU is a new type of foaming material with excellent performance. It retains the excellent properties of TPU materials and also has excellent wear resistance, high mechanical strength, high resilience, resistance to bending and folding, hydrolysis resistance, oil resistance, low yellowing, and small permanent compression deformation.
Products made of ETPU material are soft, lightweight, and breathable, making it a new type of material in the high-end shoe material field. In addition, it has a very broad application prospect in shock absorption, packaging, automotive interiors, sports equipment, children’s toys, insulation and other fields.
We use physical foaming method and supercritical fluid technology to expand the thermoplastic polyurethane material. By changing the temperature and pressure, the equilibrium state of the polymer/gas homogeneous system inside the material is destroyed, and bubble nuclei are formed and grow inside the material to form foamed polyurethane material. After foaming, TPU particles can expand to 5-8 times their original volume like popcorn, with a large number of closed pores ranging in diameter from 30 to 300 microns. These closed pores can give the foamed particles excellent resilience.
