Medical device engineers are always looking for new ways to make devices smaller and thinner, especially catheters, endoscopes, and other devices for minimally invasive procedures.

Medical device engineers are always looking for new ways to make devices smaller and thinner, especially catheters, endoscopes, and other devices for minimally invasive procedures. With walls as little as 0.0001" - 0.0005" thick (compared to 0.008" or greater for FEP heat shrink tubing), PET heat shrink tubing is ideal for use in medical devices because it can be left in the finished device without significantly affecting the profile (size). It combines incredible strength and durability with extraordinarily thin walls.

Applications include:

  • Braid termination: With high hoop strength, PET can capture a braid and prevent it from rising up.
  • Variable-stiffness shafts: Because of its ultrathin walls, PET heat shrink tubing can add stiffness to some or all of a shaft without adding to the profile.
  • Electrical insulation: Because of the high dielectric strength of PET, it is ideal for use in energy-generating or sensing devices.
  • Pad printing or marking: Our custom configurations allow for pad printing or marking the tubing to avoid printing directly on a device.
