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.

Polyurethane Gaskets for High Impact Applications

Among the many benefits of polyurethane gaskets includes superior resistance to tears, abrasion, and solvents, as well as superior bonding capabilities, high load bearing capacity, and long-lasting service life. While polyurethane is not ideal for high temperatures, it can resist cracking in even the lowest of temperatures. Gaskets made from polyurethane also perform well in the presence of greases, oils, fats, ozone, and some moderate chemicals. These gaskets are the preferred choice for high impact applications, such as wear pads, machine mounts, and aerospace and automotive components.

Ace Seal provides high quality gaskets for all types of industries and applications. We can work with you to create the custom polyurethane gaskets you need. Contact us today to get started.
