混炼型聚氨酯不仅具有优秀的物理机械性能,而且能够在常规橡胶设备上加工。本文论述的是为液-气悬挂装置之类的汽车配件、输送带和橡胶奶嘴之类食品用品而开发的聚合物,并论述了具有按照传统做法难以在混炼型聚氨酯中实现的各种性能的高硬度胶料的配制方法。这些开发成果能扩大混炼型聚氨酯的应用范围,而且能提高混炼型聚氨酯在高硬度应用中与浇注型聚氨酯的竞争力。
Mastic polyurethane not only has excellent physical and mechanical properties, and can be processed on conventional rubber equipment. Described herein is a polymer developed for food products such as automotive parts such as liquid-air suspension devices, conveyor belts, and rubber pacifiers, and discusses various properties that are difficult to achieve in conventional kneaded polyurethanes The preparation of high-hardness rubber compound. These developments can expand the range of applications for compounding polyurethanes and increase the competitiveness of compounding polyurethanes with casting polyurethanes in high hardness applications.
