混炼型聚氨酯是一种具有极好耐磨性和强度性能的聚合物,并可以在传统的橡胶设备上加工。现有混炼型聚氨酯主要用于需要利用这些性能优势的场合。一种新开发的聚合物还具有汽车工业中应用所需的极好耐渗透性和耐流体性能。针对与食品接触的FDA应用场合,另外还开发了一种聚合物, Mastic polyurethane is a polymer with excellent abrasion and strength properties that can be processed on conventional rubber equipment. The existing hybrid polyurethanes are mainly used in applications where these performance advantages need to be exploited. A newly developed polymer also has the excellent resistance to permeation and fluid resistance required for automotive applications. For FDA applications in contact with food products, a polymer has also been developed,
