In the high viscosity reaction system, twin screw extruder has many advantages that traditional equipment can't reach, because of strong heat and mass transfer, interface renewal capability, narrow residence time distribution, excellent heat transfer and stripping ratio surfaces.
TPU thermoplastic polyurethane is polymerized by diphenylmethane diisocyanate (MDI), toluene diisocyanate (TDI), macromolecular polyols and chain extenders. It has excellent comprehensive properties such as high strength, high toughness, wear resistance, and oil resistance, good processing performance, and good biocompatibility. It is widely used in spandex, shoe materials,3D printing filaments, 3C covers, films, functional films, composite leather, pipes, sports protection equipment and other fields.
