These materials are exceptionally soft, aromatic polyurethane elastomeric alloys which can be used as a substitute for rubber, silicone or latex in many applications. These materials can be processed using conventional extrusion, injection and blow molding methods and is an optimal material for applications requiring elastic properties, such as compliant/ noncompliant balloons, as well as endoscopic or laparoscopic inflation bags.

These materials are listed under the trade names:

Chronoprene and Polyblend
