New PEEK-based extrusion provides “shrink to fit” layer of protection that is impervious to extreme environments.

ORANGEBURG, S.C., February 16, 2006 - It’s considered the highest performing thermoplastic material due to its ability to withstand extreme temperatures, intense pressure and caustic fluids. Now Zeus, Inc., has taken PEEK, a linear, semi-crystalline aromatic polymer, to an entirely new level of performance with the introduction of PEEKshrink™ heat-shrinkable tubing. The new extrusion provides a “shrink to fit” layer of protection for sensitive wires and other components used in medical devices, fluid handling systems, aeronautics and automobiles, electronics, telecom hardware and oil exploration equipment.

Positioned as an alternative to traditional protective coatings like fluoropolymers, PEEKshrink™ heat-shrinkable tubing is ideally suited for challenging environments where extreme heat or cold, intense pressure, chemicals, water, or dielectric interference pose a threat to wires and electrical components. When shrunk onto components, PEEKshrink™ heat-shrinkable tubing forms an impenetrable “second skin” that is impervious to contaminants, preserving the integrity and performance of whatever is inside. The polymer’s inherent purity and lubricity make it an ideal choice for analytical and life sciences applications.

Zeus’ experience with PEEK in terms of material modification and extrusion has enabled the company to elevate several key performance attributes of PEEKshrink™ heat-shrinkable tubing, giving design engineers more options, says Zeus Director of Research and Development Bob Ballard. “PEEK is a preferred polymer for many high performance applications due to its impervious nature and superior wear resistance. By modifying the material and extruding it in a heat shrinkable format, it becomes very attractive in a new role as a lightweight, super tough insulation material. PEEKshrink™ has a continuous service temperature of 400°C (752°F) (N.E.M.A. MW 1000) and a glass transition temperature (Tg) 20°C (68°F) higher than regular PEEK. Its superior lap sheer bond strength and abrasion resistance makes it very attractive for a wide range of medical and industrial applications.”

Extensive testing has resulted in highly reliable, predictable shrink performance. PEEKshrink™ heat-shrinkable tubing has a shrink temperature of 343°C to 385°C (650°F to 725°F). It has a consistent shrink ratio of up to 1.2:1.

Zeus routinely extrudes PEEKshrink™ heat-shrinkable tubing in lengths up to 1,000 feet. It also is available in standard straight length configurations of four feet. Zeus’ precision extrusion capabilities ensure consistent wall thicknesses. There are no seams, weak points, or holes that might compromise its protective capabilities.

PEEKshrink™ heat-shrinkable from Zeus has been commercialized and is available on a global basis. It is available in standard and customer-specific configurations.
