The application fields of TPU film generally have the following aspects:
(1) Waterproof and moisture permeable TPU film for textiles The introduction of high-tech hydrophilic groups makes the TPU film have excellent moisture permeability in addition to high water repellency. This material breakthrough combined with the textile processing technology has greatly increased the added value of textiles. Representative DingZing's Dintex brand and Germany's Goretex brand. It is popular among consumers as a new and practical fabric.
(2) Non-yellowing series TPU film for ultraviolet radiation protection.
(3) Hot melt adhesive film TPU film for bonding.
(4) TPU film used on shoe materials has good printability and easy processing, making TPU a special shoe material film for shoes, casual shoes and sandals. For example, internationally renowned sports shoes brands such as Nike, Reebok, Converse, Adidas and other well-known domestic brands such as Anta, Li Ning, Xtep, and Hongxing Erke are all loyal users of TPU film. In addition, TPU film is also the best choice for some three-dimensional trademarks.
(5) The TPU film on the blown product is worth noting that since the ratio of the raw material and the temperature at the time of reaction are difficult to control when the TPU is synthesized, and the instability of the TPU itself causes the thickness to be poorly controlled, the manufacturer usually does not The area of the film is used as a measure of sales. In actual sales, it is often based on kilograms as a measure of sales. Only by doing so can the true value of the amount of material be truly reflected. Companies that need to use thin film often only consider how long and how wide the material is. Therefore, the length (code) and weight (kg) of the TPU film often need to be converted. The market price of the TPU film is about RMB 70/kg, and its price changes with the increase and decrease of petroleum and its synthetic raw materials.
