What are the advantages of the new TPU film process
TPU film production process mainly uses the blown film method and cast method. However, the production value of TPU film produced by these two methods is low, energy consumption is high, the cost is high, and it is difficult to constitute large-scale production. The film produced by the calendering process has low physical loss, excellent quality and beautiful appearance, and the TPU film prepared by the calendering method can improve the previous process problems. Calendering method also has the characteristics of large mixing capacity, short time and high production efficiency; it is beneficial to complete mechanical and automatic operation. Calendering of films can effectively control the film uniformity. Calendering is now widely used in the PVC film production industry, but as a new environmentally friendly material to replace PVC, the main skill difficulty of TPU film calendering is in maintaining the excellent physical properties of TPU.
