Which type of 2:1, 3:1 or 4:1 heat shrink tubing to use, heat shrink
tubing comes in an varied temperature and forms of
flexibility polymers from PVC | Polyolefin
| Polyolefin low smoke | Polyolefin Adhesive lined | Elastomer | Kynar
| Viton to PTFE, the higher the temperature equals higher the costs for that
particular polymer for heat shrink tubing.
We can offer a Silicone Rubber heatshrink 1.7:1 but will be to
special lead time conditions and set minimums.
2:1 Layflat PVC, -20C to +85C.
Semi rigid supplied flattened with an extremely thin wall.
2:1 Heat Shrink PVC
Semi flexible, great for shrinking down around Low Voltage busbars
Polyolefin, 3:1 and 4:1 Adhesive lined, -55 to +110C
Thin wall, inner adhesive lining provides
excellent moisture environmental sealing.
Polyolefin Heat Shrink Tubing, -55C to +135C
Thin wall, flame retardant & non flame retardant
2:1 Low Smoke LSOH, -55C to +125C
No halogens present in low smoke LSOH - LSZH
Elastomer Heat Shrink Tubing, -75C to +150C
Oil & Diesel resistant, flexible, medium wall
Kynar Heat Shrink Tubing, -55C to +175C
Mechanical strength, high chemical & punctureresistance.
Viton Heat Shrink Tubing, -55C to +200C
Viton, chemical resistant, oil & diesel
resistant. Viton practically covers all areas, that's why its expensive.
Viton-plus, -55C to +220C
As Viton but with added 10% temperature operating.
PTFE Heat Shrink Tubing, -70C to +260C
UV resistant, non stick properties, protection of
harmful moisture damage.
Silicone (Silicon) Rubber, 1:7:1, -75C to +250C
Extremely flexible in design, highly flame
retardant, good chemical and solvent resistance, ability to withstand exposure to sterilisation applications.
Example: If the substrate to be insulated is OD 6mm
at temperatures of +200C, then using either a Viton
or PTFE material fits the bill for your needs.
Alternatively, if your need is for abuse protection but with oil and diesel protection
then consider Elastomer at +150C over Viton at +200C, as Viton is a very expensive material to
purchase, even if your ID size is considerably over 25.4mm as the higher the size, temperature
and material, so increases the costings for that
polymer material. Consider your options wisely, always enquire before purchasing your tubing.
When cutting these polymers to the desired length, special care has
to be taken to ensure smoothly cut ends with sharp cutting equipment as poorly cut edges can
cause the material to split during heat shrinking process.
is advisable to always start
from the middle working outwards so the polymer
grips the area to avoid slipping and gradually
proceed to one end and then from the middle again
to the opposite end, which avoids air being trapped under the tubing and by starting from the
middle stops the polymer from slipping along the object being insulated.
Heat shrinks will also shrink longitudinally
(horizontally), you could be looking at shrinkage from +/-5% to +/-15% this has to be considered when cutting.
By heat shrinking the ends first then the middle section, using this
method is problematic as air gets trapped in the tubing and prevents the middle section from fully shrinking.
If the object to be covered is Metal or Conductive,
care must be taken to ensure the metal is pre-heated to avoid cold spots as this will give an unsightly appearance of the heat shrink tube.
If after going through all this, you are still struggling to find
a suitable "heat shrink" for your application, contact us as we just might be able
to offer something less costly to use more successfully on your finished assembly.

Smooth bore, Crush resistant (used in turbines), Spiralwrap AS41088.
Polytetrafluoroethylenes (PTFE) are different from other known polymer insulated custom
profiles, these components continually and successfully operate at very high temperatures
which are far better than most polymers around today. They have the best chemical resistance,
resistant to acids and resistant to alkalis. We offer a variety of spaghetti tubing, sleeve, spiral
wrap, convoluted conduits in various types and wall thicknesses.
