Compared to ordinary EVA, E-TPU sole material , has the advantages of light weight, high elasticity, energy storage, abrasion of recyclable, light weight, high elasticity, energy storage+return, abrasion resistance, temperature range and other advantages, especially with the fatigue resistance of haze under repeated impact, especially suitable for the production of sports shoes. Because of its excellent strength and high elasticity, high buffer performance, outside the field ETPU has been used for sports protective equipment production, such as sports; the track, protective pads, sports helmets etc.:
Product introduction Guided by gas phase differentiation, TPU materials are made into ultra-light expanded TPU beads with high resilience. Like popcorn, these beads can expand 5 to 8 times of the original size. There are numerous cells whose diameters range from 30 to 300um containing plenty of air inside the beads.
The closed cells give low density, high resilience and elasticity to the expanded beads, compared with traditional foaming materials. When made into soles, countless beads are turned into needed shapes through steam molding process during which the surfaces of beads melt a little to adhere into fixed geometry, while interior cells do not change.
The sole made from expanded beads compresses to half the size under impact, largely reducing the pressure on the foot. And the sole springs back into its original shape immediately after impact. |
