PZ73PU
■ 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。

■Overview of Products
Polyurethane (PU) is mainly characterized by oil resistance, wear resistance, low temperature resistance, aging resistance, high hardness, excellent elasticity and good anti-toxicity. It is often used in high-hardness particles and medium pipelines containing gas and liquid. Its sealing performance is good and its wear resistance is high. Polyurethane has a good name of "wear-resistant rubber", and its oil resistance is no less than that of nitrile-butadiene rubber, which is equivalent to polysulfide rubber. It is very suitable for all kinds of medium pipelines which require high sealing and high strength particle erosion.
