Abstract

Polymer blends having improved torque transmitting properties are disclosed.
The polymer blends include polyetherurethane and a concentration of polyetherester sufficient to provide the polymer blend with a 37 °C dynamic torque value greater than 40 % of the polymer bland's 25 °C dynamic torque value. The polymer blend can be thermally processed to form small diameter tubing suitable for general purpose catheters requiring both a high degree of maneuverability and sufficient resiliency to avoid tissue perforation.
