Ultra Thin Walled Lay Flat TubeThe evolution of an ultra thin walled, small diameter urethane tube, Polyzen, Inc. has identified an unmet need in the medical device arena. Through an extensive background in polymer processing, Polyzen has leveraged its expertise in urethane formulation and compounded a solution that can be extruded as a small diameter ultra thin wall tube. These tubes can be utilized as a disposable sheath for fiber optics or be produced small and thin enough to pass through a 3-mm ID channel for a diagnostic scope.

Lay flat tubing is a process that has been around for many years and is most commonly utilized in packaging applications. Typically these lay flat tubes are extruded out of an olefin based material, like polyethylene, and usually above 1.5” in lay flat width. Polyzen has found a need in which certain medical applications require a special polymer, like urethane or nylon, which is less than 1” in lay flat width and a relatively thin gauge.

"Polyzen has perfected the extrusion process for small diameter, thin walled lay-flat tubing". says Rubin Shah, Director of Business Development. "Expanding our capabilities beyond more ubiquitous higher thickness tubes has given Polyzen a clear advantage over its competitors", he adds.

The lay flat tubing process is advantageous for the production of a seamless tube, which can be delivered in continuous roll length and be cut to any size relevant to the specifications that are required. Applications for lay flat tubing are extensive; in the medical realm, this process is now being utilized to construct sheaths to be used as barriers for colonoscopes, endoscopes, speculums, probes and many other devices requiring protection from moisture, blood, or bacteria prevalent within the body. These sleeves provide a cost advantage over current practice of extensive cleaning or reprocessing.

Polyzen's capabilities include, but not limited to, producing thin wall tubing with a gauge ranging from 0.001” – 0.005” with a tolerance of +/- 25% of thickness. The small diameter lay flat tubing can be extruded at a width ranging from 0.25” up to 3”. All extrusions are done within a class 10,000 clean room environment.
