Polyurethane (PU) boasts excellent properties including oil resistance, abrasion resistance, low-temperature resistance, anti-aging performance, high hardness, superior elasticity and good chemical resistance. It is widely used for pipelines transporting hard solid particles as well as mixed gas-liquid media, featuring reliable sealing performance and heavy-duty wear resistance.

Known as “wear-resistant rubber”, polyurethane delivers oil resistance equivalent to polysulfide rubber and no inferior to nitrile butadiene rubber (NBR). It is highly suitable for all medium pipelines that require tight sealing while enduring intense erosion from hard solid particles.

■ 产品概述

聚氨酯（PU）主要具有耐油，耐磨，耐低温，耐老化，硬度高，弹性优并防毒性能良好等特性，常适用于高硬度的颗粒及含有气体液体等介质管道，其密封性能良好且具有高强度耐磨性能。聚氨酯有“耐磨橡胶”的佳称，其耐油性也不低于丁腈橡胶，与聚硫橡胶相当。非常适用于各种要求密封性高又有高强度颗粒物冲刷的介质管道等。
