The E-TPU foamed material is a novel polymer material formed by aggregating a plurality of TPU foamed small balls with high elasticity and light weight, consists of amorphous and rigid molecular chains, and does not contain any flexible chain segment in the molecular structure; therefore, the ETPU material not only has the strength and dimensional stability of amorphous resin, but also has the chemical resistance, fatigue resistance and wear resistance of crystalline resin. After foaming, the granular material expands 5-8 times in volume, the diameter of cells is not more than 30-300 microns, the size and shape of the granular material are the same as that of popcorn, and the density of the granular material per cubic centimeter is 0.15-0.25 g, so the granular material is called the popcorn in the industry; the TPU material overcomes the defects of heavy weight, high hardness, poor damping performance and the like of the TPU material, and has the advantages of lighter weight, stronger air permeability, environmental protection, wear resistance, high elasticity and yellowing resistance.
The E-TPU material has two preparation modes, one is to firstly foam and form a plurality of TPU particles into a foaming particle forming body once, then carry out secondary foaming forming and aggregation on the foaming particle forming body to form a finished product, and the other is to directly carry out injection molding to form a TPU injection molding body, and then carry out primary foaming forming on the TPU injection molding body to form the finished product. The foaming forming process has two physical and chemical modes, wherein the physical foaming is to enable the supercritical fluid to permeate into the TPU injection forming body under the environment of high temperature and high pressure, and then enable the TPU injection forming body to form bubble cores for expansion and shaping through rapid pressure relief, so that a foaming product is obtained. The traditional insole is basically made of TPU materials through physical foaming, and in the foaming process, in order to ensure that supercritical fluid can completely permeate into a TPU injection molding body, so that the foaming quality is ensured, long time is usually needed for the supercritical fluid to completely permeate into the TPU injection molding body, and therefore the traditional insole manufacturing method has the defects of long foaming time and low production efficiency.
