O-Rings & Seals | AU/EU
One must differentiate between polyester urethane (AU)
and polyether urethane (EU). AU type urethanes exhibit
better resistance to hydraulic fluids. Polyurethane elastomers,
as a class, have excellent wear resistance, high
tensile strength and high elasticity in comparison with any
other elastomers. Permeability is good and comparable
with butyl.
