Thinner walls, smaller size
Advantages of PET tubes
● Ultra-thin wall, ultra-high strength
● Extremely smooth inner diameter surface for smooth outer surface of processed components
● Relatively low shrinkage temperature
●High axial shrinkage for improved welding results
● Can be "heat-set" and therefore stable at defined temperatures
●Can be printed for marking of supervisors
Common applications (conduit processing)
● Tube welding (variable stiffness catheter) ● Braid termination
● Balloon welding ● Masking in the coating process
● Main tube lamination ● Micro hose clamps (compliant balloons etc.)
● Tip forming ● Encapsulation, strapping and strain relief
● Reflow soldering, catheter lamination (RX ports, etc.)
PET material properties

Stripping situation | PET comes off most common thermoplastics very easily. However, certain low durometer polyurethanes tend to to adhere to PET, but may require a standstill period (approx. 1 hour) and may not be suitable, which needs to be tested and verified before use. | |
