PEEKshrink heat-shrinkable tubing provides a “shrink to fit” layer of protection for sensitive wires and other components used in fluid handling systems, aeronautics and automobiles, electronics, telecom hardware and oil exploration equipment. When shrunk onto components, the 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 ideal for analytical applications.
