   Advantages: 1.PU materials display higher mechanical strength ,high abrasion, wear and extrusion resistance, high pressure load capacity,as well as a high tear and elongation at break resistance. Also have good flexibility and very good aging and ozone resistance.   2.PU seal is mainly used in oil cylinder, can be easily fixed and scrape the dust and dirt off the piston.   3.PU seals working in a reciprocating motion. It can take extremely high pressure(max about 750kg/cm2)with a slower motion of speed(about 300mm/sec).When the working pressure increase. The lips of PU seals will enlarge,contacting the surface by the pressure of fluid. 4.PU seal has good mechanical,wear-proof and oil-proof property ,most frequently used in hydraulic oil cylinder with medium and high pressure.    5.PU seals are the most important parts for Hydrodynamic system . It may produce and put a lot power with an extremely small motor,which can activate heavyduty machinery.           Our factory's machine
