TPU(Thermoplastic polyurethanes), Thermoplastic TPU elastomer is made by extruding and mixing MDI containing NCO functional groups with POLYOL and 1.4BG containing OH functional groups. Due to its good elasticity, physical properties, and various mechanical strengths, it is widely used in injection molding, extrusion, rolling, and dissolution into solution resins. It is a plastic material commonly used by plastic processing workers, and its products cover the range of industrial applications and household necessities.
In recent years, due to the continuous development of new products, the usage of thermoplastic PU elastomers has been continuously increasing, creating new opportunities for plastic processing industry workers to achieve low cost and high added value. This is the reason why TPU laminating machine is more and more popular nowadays.
TPU (thermoplastic polyurethane) is increasingly popular due to its superior performance and environmental protection concept. Wherever PVC is used, TPU can become a substitute for PVC. But the advantages of TPU are far behind those of PVC. TPU not only has the characteristics of high tension, high tensile strength, toughness, and aging resistance, but also is a mature environmentally friendly material. TPU has been widely used in shoe materials, clothing, inflatable toys, water and underwater sports equipment, medical equipment, fitness equipment, car seat materials, umbrellas, suitcases, leather bags, etc. People in these industries are quite familiar with Kuntai's TPU laminating machine.
TPU film is made from TPU granular material through processes such as rolling, casting, blowing, and coating. Widely used in sports shoes: trademark decorations on the sole and upper, airbags, air cushions, oil bags, etc. Nowadays, there are two trends in the application of TPU film in sports shoes: one is the trend swept by women's sandals, which is to directly cut, screen print and color high transparency TPU film, or attach it to the fabric base to form a mesh cloth, high-frequency forming and bonding it to the upper of the shoe, with functional and decorative effects. The second is to use waterproof and breathable TPU film and shoe material cloth to achieve the effect of waterproof and breathable.
Along with the deveopment of TPU film technology, TPU laminating machine also encounter continuous improvement.
