Heat Shrink Tubing TMW
Adhesive-Lined Translucent Semi-Rigid Polyolen
Product description
3M™ Heat Shrink Tubing TMW is
a semi-rigid, translucent heat-shrinkable
polyolen tubing that is co-extruded and
selectively cross-linked with an integral,
meltable inner wall.
When heated in excess of 135°C
(275°F), 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 exible bond with a wide variety
of rubbers, plastics and metals. Upon
cooling, TMW tubing provides a tough,
protective and insulating barrier, highly
resistant to penetration by moisture,
chemicals and solvents.
TMW tubing is rated for continuous
operation at temperatures from –55°C
(–67°F) to 110°C (230°F) and will
withstand higher operating temperatures
for brief periods. Adhesive reow will
occur at temperatures above 80°C (176°F).
Typical applications
The primary application for 3M TMW
tubing 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
TMW tubing is available color coded by
diameter. Please see chart below.
Standard packaging
TMW tubing 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 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 tubing
183-1.500.
