The superior lubricious properties of PTFE make it an excellent material choice for lining catheter lumens. Conventional dip-coated or film cast PTFE Liners are mechanically weak, exhibit low tensile strength and are prone to inconsistencies. Junkosha PTFE Liners are robust, high in tensile strength, have superior consistency in elongation and elastic properties, and are available with ultra thin walls to meet critical catheter dimension requirements. Junkosha PTFE Liners are available with optimized etching and surface treatment to enhance reflow and adhesion even in the most demanding tapered catheter designs.
