New TPU film for excellent performance close to practice rolling

TPU film is a plastic material commonly used plastics processing industry , which covers a range of products made ​​from industrial applications and civilian necessities . Baoding Bonte Polymer New Materials Co., new product research and development after nearly a year of effort, successfully developed can be used to practice the preparation of dense TPU film calendering new materials and processes have been recognized by secret practice rolling through the downstream customers.Sellotape

Currently , TPU has been widely used in many fields of automobile manufacturing, refrigerator manufacturing , transportation, civil construction , footwear , synthetic leather , textile , electronics, petrochemical, mining machinery , aerospace, medical , agriculture , etc., with other plastic materials can not match high strength, good toughness , wear resistance, cold, oil , water , anti-aging , weather and other features , but also has high water resistance , moisture resistance, wind, cold, antibacterial, antifungal , warm , UV and energy release and many other unique features.Washi tape

TPU film manufacturing process used mainly Blown and cast method. However, these two methods the use of low yield films produced TPU, energy consumption , high cost , difficult to form a large-scale production . Polymer New Materials Co., Ltd. Baoding Bonte research team took more than a year of continuous research, and finally developed in the basis of maintaining the original physical properties to meet the rolling process to produce new TPU material. Calendering process to produce low loss film properties , excellent quality , beautiful appearance, expect a single set of four- roll calender mixing equipment up to 6,000 tons of annual output .

Prepared using secret training calender TPU film can greatly improve the above problems. Closed mixing method ( mixing method) works is by relative rotation of the two rotors in the mixer , the material from the feed port into the nip by sandwiching the rotor compression and shear , through the nip after the sharp edge across the top tie is divided into two parts, the front and rear respectively, along the gap between the wall and the rotor and then back above the nip .

In the week the flow around the rotor , the material being cut everywhere and friction , so that a sharp rise in temperature of the material , the macromolecules uniformly cut, increase mobility . According to the working principle of mixing method , the method is applied to products prepared by mixing TPU downstream , can effectively control the film crystallization point and the emergence of plot material , particularly suitable for the production of TPU film.Masking tape

While mixing method also has a mixing capacity, time is short, high production efficiency ; safe and convenient operation, reduce labor intensity ; beneficial to realize the advantages of mechanical and automation . Meanwhile , prepared by calendering the film , can effectively control the film uniformity . Banburying rolling method has been widely used in PVC film industry , but as a new type of environmentally friendly alternative to PVC materials , TPU banburying calender has not been reported. Its main technical difficulties in maintaining excellent physical properties of TPU basis so that new materials are suitable for mixing TPU calendering process .Wholesale masking tape
