URETHANE (EU/AU)

Urethanes are noted for outstanding resistance to abrasion and tear. Urethanes provide the highest available tensile strength among all elastomers while providing good elongation characteristics. Ozone, oxidation, sunlight, weather, oil and casual gasoline exposure are environments suited for urethane applications. Ether based urethanes (EU) are directed toward low temperature flexibility applications. The ester based urethanes (AU) provide improved abrasion, heat and oil swell resistance.

Urethanes are not recommended for alkalis, acids and oxygenated solvents. Ester based urethanes are not typically recommended for hot water, steam and high humidity applications, but can be formulated to improve resistance to these properties.
