Polyurethane (AU, EU)

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.

• Mineral oil and grease

• Silicone oil and grease

• Water up to 50°C (125°F)

Not compatible with:
