PZ73PU
■ 產(chǎn)品概述
聚氨酯（PU）主要具有耐油，耐磨，耐低溫，耐老化，硬度高，彈性優(yōu)并防毒性能良好等特性，常適用于高硬度的顆粒及含有氣體液體等介質(zhì)管道，其密封性能良好且具有高強度耐磨性能。聚氨酯有“耐磨橡膠”的佳稱，其耐油性也不低于丁腈橡膠，與聚硫橡膠相當(dāng)。非常適用于各種要求密封性高又有高強度顆粒物沖刷的介質(zhì)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.
