O-ring is suitable for installation in all kinds of mechanical equipment, in the specified temperature, pressure, as well as different liquid and gas medium, at rest or motion of the sealing effect. In machine tools, ships, automobiles, aerospace equipment, metallurgical machinery, chemical machinery, engineering machinery, construction machinery, mining machinery, petroleum machinery, plastic machinery, agricultural machinery, and all kinds of instruments and meters, a large number of applications of various types of sealing components. Polyurethane (PU) O Ring Seals Featurs: Polyurethane is an elastomer composited of organic units joined by urethane links. This material is used to make everything from foam sponges to automotive bushings to synthetic fibers like Spandex. Polyurethane o-rings, polyurethane gaskets, and polyurethane seals are ideal for applications that need rubber- or plastic-characteristics, but with the durability to survive challenging environments that these materials could not. They exhibit excellent abrasion resistance, chemical resistance, elasticity, and rebound. Polyurethane is also highly resistant to abrasion, cuts, cracking, high impact, and heavy loads.
