PU - Polyurethane

Features : Millable Polyurethane is outstanding over most other O-ring elastomers in abrasion resistance and tensile strength. They are also compatible with hydraulic fluids, weak acids and bases, and mixtures containing less than 80% aromatic constituents. Good low temperature flexibility is also a feature of many Millable Polyurethane elastomer compositions.

Application : Seals for high hydraulic pressures. Situations where highly stressed parts are subject to wear.
