[0002] Thermoplastic TPU elastomer is made by extrusion and mixing MDI containing NCO functional groups and POLYOL and 1.4BG containing OH functional groups. Due to its good elasticity, good physical properties and good mechanical strength, it is widely used in processing methods such as injection, extrusion, calendering and dissolving into solution-type resins. It is a plastic material frequently used by plastic processing industries. Its products cover the range of industrial applications and civilian necessities. TPU film is made on the basis of TPU granules through special processes such as calendering, casting, film blowing and coating. The thickness is 0.01 to 2mm.
