ChronoFlex AR®

STRENGTH, ELONGATION AND DURABILITY IN LIQUID FORM.  

Solution-based polycarbonate urethanes

The ChronoFlex AR and ChronoFlex AR-LT product lines are polycarbonate urethanes designed for molding, casting and dip coating applications. These unique materials are fully synthesized in liquid providing superior strength & elongation while maintaining the inherent polycarbonate advantage of long-term permanent durability and resistance to Environmental Stress Cracking (ESC).  Additionally, they may be electrospun or used in water emulsion processes. 

ChronoFlex AR & AR-LT polymers are ideal in applications requiring exceptional flexural endurance such as artificial heart diaphragms, vascular grafts, or for use in the fabrication of blood contact surfaces, such as coatings.

 

The ChronoFlex AR & AR-LT demonstrates an inherent low-tack property, which allows for pulsatile flow in-situ, an innovative characteristic optimal for devices such as VADs and artificial valves components.

 

This product line is offered in a wide range of viscosity/concentration configurations based upon specific product requirements.
