Ultrahigh Vacuum (UHV) Shrink Tubing
PEEK Shrink Tubing
PEEK shrink tubing is considered the highest performing thermoplastic material due to its ability to withstand extreme temperatures to 250°C, high pressure, and chemical fluids. PEEK shrink tubing provides a "shrink to fit" layer of protection for critical components and wiring used in ultrahigh vacuum applications to 1 x 10-10 Torr.
FEP Shrink Tubing
FEP shrink tubing offers a great dielectric strength at a much lower cost than PEEK but is limited to a lower temperature and vacuum range of 200°C and 1 x 10-8 Torr.
