What is TPU tape casting film?

TPU thin films are prepared by special processes such as calendering, casting, blowing and coating on the basis of TPU granular materials. Thickness 0.01 to 2 mmTPU (Thermoplastic polyurethanes), thermoplastic TPU elastomer, is made of MDI containing NCO functional group, POLYOL containing OH functional group and 1.4BG by extrusion mixing. Because of its good elasticity, good physical properties and good mechanical strength, TPU elastomer is widely used in injection, extrusion, calendering and dissolution into solution resin. The way is the plastic material which is often used by the plastic processing industry. Its products cover the range of industrial applications and civil necessities. In recent years, due to the continuous development of new products, the use of thermoplastic PU elastomers is increasing continuously, creating a new opportunity for plastic processing industry with low cost and high added value.

TPU thin films are prepared by calendering, casting, blowing and coating on the basis of TPU granular materials. At present, it is widely used in sports shoes: trademark decoration on sole and upper, airbag, air cushion, oil bag, etc.

There are two trends in the application of TPU film in sports shoes: one is the popular trend caused by women's sandals, that is, cutting high transparent TPU film or directly, printing and coloring screen, or laminating cloth base into mesh cloth, etc. High cycle wave forming and bonding on the upper of shoes has the effect of functionality and decoration. The other is to use waterproof and moisture permeable TPU film and cloth for shoes to achieve the effect of waterproof and moisture permeability.

TPU (thermoplastic polyurethane) is increasingly popular because of its superior performance and environmental protection concept. At present, TPU can be used as a substitute for PVC wherever PVC is used. But the advantages of TPU are beyond the expectation of PVC. TPU not only has excellent characteristics of high tension, high tension, toughness and aging resistance, but also is a mature environmental protection material. At present, TPU has been widely used in shoes, ready-made clothes, inflatable toys, water and underwater sports equipment, medical equipment, fitness equipment, car seat materials, umbrellas, suitcases, bags and so on.
