Polyurethane (AU/EU)

There are two types of polyurethane, polyester urethane (AU) and polyether urethane (EU). Both exhibit outstanding abrasion and tear resistance, and have the highest tensile strength available among all elastomers, while also exhibiting good elongation characteristics.

Ether-based urethanes (EU) show better flexibility in low-temperature applications, while ester-based urethanes (AU) provide improved abrasion, heat, and oil swell resistance.
