Nordson - Polyester (PET) Heat Shrink Tubing
The world’s thinnest, smallest, & strongest heat shrink tubing. Nordson MEDICAL’s polyester (PET) heat shrink tubing is ultra-thin-walled, high-strength, optically clear or pigmented and heat shrinkable. This Vention Medical technology was developed specifically for the medical device industry, and has been at the leading edge of medical device tubing since its creation.
Characteristics
PET Heat Shrink Tubing is an extremely unique material with impressive characteristics including:
- Ultra-thin wall, ultra-high strength, and high dielectric strength
- Can be recovered at relatively low temperatures
- Axial shrinkage pulls components together
- Can be transformed into custom parts by drawing/shrinking onto a shaped mandrel(conical, square, triangular, etc.)
- Can be “heat-set” so that it is stable up to a rescribed temperature
- Can be printed for shaft marking/indicating
Applications
- Braid termination
- Insulation
- Encapsulation, bundling, and strain relief
- Masking for coating procedures
- Micro-hose clamps
- Tube joining (variable stiffness catheters)
- Balloon bonding
- Shaft lamination
- Tipping
- General reflow (RX ports, braided shaft lamination, etc).
Specifications
Diameter range: 0.006” – 1.5” (0.15 – 38.1 mm)
Wall thickness range: 0.0001” – 0.004” (0.0025 – 0.10 mm)
Shrink ratios: 1.1:1 up to 3:1*
Tight fit is best: 15% gap or less**

Recommended hot box range: 300°F to 450°F (149°C to 232°C)
Material Compatibility
PET releases easily from most common thermoplastics. However, some low-durometer urethanes tend to tack to the PET and may require a resting period (~1hr) or may not be compatible. Run test samples with these materials.
Tensile Strength: Very high tensile strength can be realized (>20,000 PSI)
Electrical Insulation: Good
Surface Finish: Ultra smooth, hard, glossy finish
Color/Clarity: Available in clear and a variety of opaque and transparent colors
Bondability: Can be bonded using a wide range of adhesives (surface treatment recommended)
Flex Fatigue: Very high flex fatigue properties
Biocompatibility: Meets USP Class VI and ISO 10993 requirements
Sterilization: Ethylene Oxide, Gamma Irradiation, E-Beam and Autoclave (repeat autoclaving is not recommended)
