Features of TPU laminating extrusion line: Through the co-extrusion of 2 or 3 extruders, TPU raw materials with different temperature ranges and hardness ranges are compounded and extruded at one time. Compared with the traditional composite process, it is more economical, more environmentally friendly, and more efficient to combine the high-temperature and low-temperature films off the assembly line.
TPU laminating extrusion line products are widely used in water stops, shoe materials, clothing, luggage, stationery, sporting goods, and so on.
TPU melts are sensitive to shear and temperature. Too high shear will lead to poor product performance, and too high temperatures will lead to melting decomposition, so there are certain requirements for TPU film extrusion lines and screw design.
Generally, the processing temperature and shear rate of the TPU film extrusion line are controlled by reducing the speed of the screw, but this will lead to a decrease in extrusion volume. Therefore, it is recommended to use a barrier-type forced feed screw with a smooth barrel to solve the extrusion volume problem.
TPU film has good tensile elasticity, so we must pay attention to the traction and winding process, generally in the traction process to maintain the stability of the tension and reduce the traction force as much as possible, so some equipment adopts tension closed-loop control method to achieve the constant tension of traction, ensure the stability of the tension, and wind through the gap winding method.
