Zhengzhou heavy rain after the 50 million yuan donation, so that the light of domestic goods Hongxing Erke quickly out of the circle, although the chairman and the platform anchors unanimously called on users to buy on demand, rational consumption, but the current users will still be "wild consumption" insisted to the last. Fortunately, our small editor is rational. Today, from a professional perspective, I will take you to see the application of TPU in the field of sports shoes.

 

TPU has good processing properties such as injection, extrusion, calendering, blow molding and molding. It is widely used in three shoe manufacturing projects, such as sole, vamp and fitting, and is favored by the majority of shoe manufacturers. As can be seen from the following figure, TPU covers almost all the range of shoe manufacturing process.

As an outsole, TPU can provide good wear resistance, folding resistance, fatigue resistance; The middle bottom part can be used as an air cushion to provide good resilience and shock absorption.

 

On the vamp, waterproof and moisture permeable TPU can be used as a film and shoe material with cloth. Can also be used as a special decorative effect, the method is to screen printing TPU film color, and then in high frequency forming and bonding on the vamp for decoration; In addition, TPU melt-spun spandex fly fabric or TPU synthetic leather fabric can be used as the vamp. TPU shoelaces are usually made of UV resistant TPU materials, which are stronger and more flexible than traditional polyester and nylon materials. At the same time, it has the characteristics of light weight, waterproof, dirty resistance and easy to clean. And can provide a large contact surface, effectively prevent knot loose.

 

TPU adhesive is a kind of polyurethane adhesive. The use of polyurethane adhesive in Europe and The United States has been quite common, especially in the use of footwear adhesive almost use polyurethane adhesive. The use of TPU adhesives in China is to obtain polyurethane adhesives after TPU dissolution and processing. With the development of lightweight footwear products, the advantages of TPU materials are very obvious, but the high cost of TPU restricts its large-scale application in the field of footwear.

 

At present, there is still a certain gap between the choice of TPU and the demand of rubber, EVA and other materials in shoe material production enterprises. The following figure is the current domestic shoe materials in the field of each material share statistics. In the future, TPU in the footwear sector is expected to continue to grow by 5-10%, driven by the overall sports industry and the increase of TPU consumption in the single shoe.
