Quadraflex™

The Quadarflex™ family of polyether-based medical grade thermoplastic urethanes are available in both aromatic and aliphatic chemistries. These medical grade polymers exhibit excellent mechanical properties, elasticity, biocompatibility, and softening at body temperature. Quadraflex is the most common medical grade urethane family and can be used across a range of medical markets including venous access, urology, cardiology, hemodialysis, respiratory, and minimally invasive surgical devices. Quadraflex is available in a wide array of durometers, colors and radiopacifiers.

Quadraflex™ ALE, Aliphatic Polyether TPU

Quadraflex™ ALE grades are non-yellowing and commonly used in catheter tube applications.
