TMW Tubing
Adhesive-Lined, Translucent, Semi-Rigid Polyolefin
Data Sheet
Product Description
3M
™
TMW Tubing is a semi-rigid, translucent
heat-shrinkable polyolefin tubing that is co-
extruded and selectively cross-linked with an
integral, meltable inner wall.
When heated in excess of 135ºC (275ºF),
the adhesive inner wall of the tubing is
softened and forced by the shrinking action of
the outer wall into contact with all underlying
surfaces and small voids. The adhesive forms
a flexible bond with a wide variety of rubbers,
plastics and metals. Upon cooling, 3M TMW
tubing provides a tough, protective and
insulating barrier, highly resistant to
penetration by moisture, chemicals and
solvents.
3M TMW tubing is rated for continuous
operation at temperatures from -55ºC (-67ºF)
to 110ºC (230ºF) and will withstand higher
operating temperatures for brief periods.
Adhesive reflow will occur at temperatures
above 80°C (176°F).
Typical Applications
The primary application for 3M TMWtubing
is in the manufacture of heat shrink butt
connectors, disconnects, ring terminals and
fork terminals. Other applications include
braided-shield pigtails, mechanical assemblies,
electronic components, electrical wire splices,
breakouts, solder joints, delicate wire
terminations and end-sealing of electrical
cables.
3M TMW tubing can withstand the
crimping force of standard crimp tools without
puncture or splitting during heat recovery. The
tubing remains round when cut, making it
ideal for use in high speed processing and
assembly equipment.
Standard Colors
3M TMW tubing is available color coded by
diameter. Please see chart below.
Standard Packaging
TMW is supplied in cut pieces. Standard
lengths are available in 10,000 piece cartons,
other lengths and diameters are available
subject to factory quotation.
Ordering Information
Order 3M TMW tubing in the size equivalent
to the expanded inside diameter required.
Always order the largest size that will shrink
snugly over the component to covered. Non-
standard diameters and cut lengths are
available subject to factory quotation.
Example: TMW Red 183-1.50
