Ether-PUR FLEX™ 84


Ether-PUR FLEX™ 84

Product Features

The Ether-PUR FLEX™ 84 tubing line is made in the U.S. from an ether based polyurethane resin. This material is much more abrasion and impact resistant than PVC while maintaining flexibility and a glass-like clarity. Urethane also possesses a high level of chemical compatibility. Since this is a pure polyurethane resin, it contains no plasticizers and has a very low level of extractables making it a great product for high purity applications. This formulation CAN be used with aqueous solutions.
