The difference between TPU and PVC materials


TPU can be divided into the polyester type and polyether type according to the soft segment structure. According to the classification of structural characteristics, TPU can be divided into full thermoplastic and semi-thermoplastic. There are no chemical cross-linking bonds between the former molecules, only physical cross-linking bonds dominated by hydrogen bonds, which are soluble in dimethylformamide and other solvents; the latter molecules contain few allophanate chemical cross-linking bonds. These chemical cross-links are thermodynamically unstable and will break at processing temperatures above 150 degrees Celsius, and will regenerate after molding and cooling. The presence of a small number of chemical crosslinks plays an important role in improving the compression set and tear set properties of the product.

 

Similar to other thermoplastics, thermoplastic polyurethanes have rubber-elastic or plastic properties at room temperature and melt at high temperatures, becoming a viscous fluid and processing as thermoplastics. Thermally expelled polyurethane forms physical crosslinks by intermolecular hydrogen bonds and has high mechanical strength. The main difference between thermoplastic polyurethane and cast polyurethane is the difference in processing and molding methods and the variety of chain extenders. Thermoplastic polyurethanes can be polymerized by the bulk melt method or by the solution method. Commercial TPU is usually granular, and can be made into various shapes or composite products by thermoplastic processing methods such as extrusion, injection, calendering, blow molding, molding, etc. Among them, extrusion molding and injection molding are the most used, about approx. account for more than 70%. TPU is also used in the manufacture of elastic fibers, synthetic leather resins, adhesives, and coatings.
