When selecting TPU plastic granules, it is essential to consider the product's intended use and the processing method. First, determine the required hardness; TPU typically ranges from 60A to 75D, with different hardness levels suited to different products. Next, select a material grade based on specific performance requirements-such as transparency, yellowing resistance, hydrolysis resistance, or flame retardancy.
The processing method is equally critical; for instance, injection molding, extrusion, and blow molding impose different requirements regarding material flowability, so the appropriate grade must be chosen. Additionally, factors such as wear resistance, oil resistance, performance across temperature extremes, and compliance with environmental standards should be evaluated. It is advisable to source materials from reputable manufacturers that offer consistent quality and robust technical support; this not only ensures product quality but also minimizes defect rates during production and enhances overall manufacturing efficiency.
