Features
Heat shrink tubing is used for reflowing material in a catheter assembly process. The only way to remove
it from the catheter after shrinking is by ‘skiving’, which not only takes significant time, but is also
risky due to the possibility of damaging the catheter in the process.
Junkosha Peelable Heat Shrink Tubing eliminates the need to skive the heat shrink material from the
catheter after the reflow process, significantly reducing both the time required to take this step and
also the risk of damaging the underlying catheter. Junkosha Peelable Heat Shrink Tubing is available in
a wide range of sizes, from ultra small for microcatheters and guidewires up to large diameter
constructs for structural heart and peripheral applications. All are available in a wide offering of
cut-to-length and slit options.
Junkosha Peelable Heat Shrink Tubing offers a streamlined workflow solution to catheter manufacturers,
helping to improve efficiency on the production line.
Benefits
Point 01
Superior Peelability
Higher performance and safer than traditional HST
Users of our Peelable Heat Shrink Tubing can easily remove the tubing by hand. Requiring only a single
slit in one end to get it started, Junkosha Peelable Heat Shrink Tubing peels easily along its entire
length without the need for additional fixtures or tools in the process.
By removing the need to skive, Junkosha Peelable Heat Shrink Tubing reduces Total Cost of Ownership
(TCO) for manufacturers by expediting the end-to-end manufacturing process and improving yields.
Point 02
Extensive Lineup
from Ultra Small to Extra Large
Our extensive lineup includes Peelable Heat Shrink Tubing suitable for devices from microcatheters to larger diameter applications with expanded inner diameters ranging from 0.38 mm (0.0150”) to 11.43mm (0.4500”).
Point 03
Customization
We provide attentive services that meet our customers' needs and requirements.
Leveraging our proprietary design techniques, we provide high-shrink ratio Peelable Heat Shrink Tubing
(up to 1.8:1) with controlled performance characteristics, wall thicknesses and elongation. Our
high-shrink ratio 1.8:1 Peelable Heat Shrink Tubing is ideal for manufacturing tapered microcatheter
shafts or where tolerance take-up is an issue. Junkosha also provides custom dimensions and other
tailored design specifications and tolerances upon request.
In addition, we also provide tubing with optimized shrinkage force and elongation characteristics to
improve the manufacturing process.
Junkosha Peelable Heat Shrink Tubing can be cut to length to meet customer requirements or shipped
with a pre-slit notch to aid operators’ ease of removal.
Fast and Easy!
Junkosha offers an accessible support system.
Technologies
Our patented technology offers superior peelability to heat shrink tubing.
Junkosha was the first company to add ease of peelability to heat shrink tubing. By leveraging our core
material capabilities, we have improved our product's performance by employing cutting-edge precision
molding, extrusion and expansion technologies.
These technologies have also allowed us to achieve consistent and repeatable shrinkage performance in
parameters such as expanded inner diameter, recovered inner diameter, recovered wall thickness and
recovered length.

*Junkosha is manufactured and inspected in mm and values in inch are for
reference only. Measurements of each dimension are performed using metric based measuring
instruments.
*The inch values are calculated from the actual measured values (metric values) using the following
formula, with one digit below the displayed digit rounded to the nearest value (numbers 5 and above
are rounded up, and numbers below 5 are rounded down). (Inch value) = (Metric value) ÷ 25.4
*Peelable Heat Shrink Tubing meets the requirement of USP Plastic Class VI. Certificates available on
request.
