PEEK tubing with a service temperature of up to 482 F has been available to replace stainless steel for weight reduction, chemical resistance, and lubricity.

PEEK tubing with a service temperature of up to 482 F has been available to replace stainless steel for weight reduction, chemical resistance, and lubricity. But Zeus Inc. in Orangeburg, S.C., thinks it's the first to develop heat-shrinkable PEEK tubing, designed for use as a protective covering. Its new PEEKshrink tubing has a consistent 1.2:1 shrink ratio and targets applications as a protective sleeve over medical devices, aerospace and automotive electronics, telecommunications components, and oil exploration equipment. A special manufacturing process is said to raise PEEK's service temperature to 752 F and its glass-transition temperature (Tg) 68° F higher than that of standard PEEK. It can replace fluoropolymer coatings because of PEEK's high resistance to heat, cold, chemicals, pressure, and dielectric interference.
