Advantages Of CPU Polyurethane Products Over TPU

CPU (cast polyurethane elastomer) has outstanding wear resistance, high elasticity and unique processing performance.Compared with TPU (thermoplastic polyurethane elastomer), CPU stands out for its excellent wear resistance (the best in elastomers) and unique processing performance. It can be in a liquid state at room temperature and can be made into products with various complex shapes through specific processing methods such as casting. This characteristic makes CPU excel in high-precision and complex structure applications, such as wear-resistant parts in mining and refining industries, rollers in textile and printing machinery. CPU products are not only wear-resistant, but also have good rebound and fatigue resistance, which can maintain stable performance for a long time. In contrast, although TPU also has excellent wear resistance and high elasticity, its processing method is completely different from CPU. TPU is solid at room temperature but can be transformed into liquid through heating or solvent dissolution for thermoplastic processing such as injection molding, extrusion and blow molding. This processing method makes TPU more flexible to adapt to market demands and achieve mass production quickly. However, in terms of wear resistance and high elasticity, CPU and TPU are equally good. CPU's unique processing performance gives it an advantage in specific application scenarios. The article intends to only focus on the positive aspects of CPU and TPU.
