Shanghai Renfos chemical Co., Ltd.

E-TPU

  1\E-TPU, is using supercritical fluid as physical foaming agent and TPU as raw material product a closed cell expanded thermoplastic polyurethane beads. The foam process causes the TPU particles to swell up to 7-10 times original volume, while at the same time greatly reducing their weight. The excellent performance of both the TPU and the foaming material into one, inherited the excellent performance TPU material: high tensile strength, elongation at break, excellent resistance to compression, high elasticity, outstanding resilience and good chemical resistance.
