Product Introduction:
TPU plastic granules are produced by extrusion and mixing. Due to their good elasticity, physical properties and various mechanical strengths, TPU has been widely used in: shoe materials, ready to wear, inflatable toys, aquatic and underwater sports equipment, medical equipment, fitness equipment, car seat materials, umbrellas, leather cases, leather bags, etc.
