Heat Shrink Tubing MW
3M™ Heat Shrink Tubing MW is a semi-rigid, 110ºC heat-shrinkable polyolefin
tubing that is co-extruded and selectively cross-linked to provide an integral,
meltable inner wall.
When heated in excess of 135ºC (275ºF), the inner meltable wall of the tubing is
simultaneously softened and forced by the shrink action into intimate contact with all
underlying surfaces, interstices and small voids. Upon cooling, the MW tubing
provides a tough protective and insulating barrier, highly resistant to penetration by
moisture and the introduction of chemicals and solvents. Adhesive reflow will occur
at temperatures above 80ºC (176ºF).
Meets requirements of:
• SAE-AMS-DTL-23053/4, Class 1*
• AMS-3634
• UL Listed, UL File E-157227
*Formerly MIL-DTL-23053/4, Class 1
Applications for MW tubing include braided-shield pigtails, electrical wiring,
mechanical assemblies, electronic components, electrical wire splices, breakouts,
connections, solder joints, delicate wire terminations, end-sealing of electrical
cables and rigid tubings.
For installation that may require rework, retrofit or repair in the field, MW tubing
offers the extra advantage of easy removability. For circuit and component
identification purposes, the tubings readily accept marking by means of print-wheel
or hot-stamp techniques.
MW tubing has a 2.5:1 shrink ratio. When fully recovered, the tubing will shrink 40%
of its original diameter. The recovered wall thickness of the tubing is proportional to
the degree of recovery.
The operating temperature range is from -55ºC (-67ºF) to 110ºC (230ºF), with a
shrink temperature minimum of 135 ºF (275 ºC), and will withstand higher operating
temperatures for brief periods.
