What is Polyurethane? General Properties, Compatibility & More
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.
If polyurethane is not chemically compatible with your application, view our chemical compatibility chart to find the material that best suits your needs.
Common applications for polyurethane gaskets, etc., include bulk material transfer systems, hydrostatic testing, liquid transfer systems, nondestructive testing, automotive, and hydraulics.
