Automotive Industry
Data Sheet
July 2019
Description
3M™ Heat Shrink Tubing SMS is a co-extruded, dual wall product. It is a composite
of a polyolefin shrinkable outer wall and a thermoplastic adhesive inner wall. 3M
SMS tubing is resistant to sever vibration, certain temperature changes, and
automotive fluids that are seen in the automotive and marine environments.

Semi-rigid 3M SMS tubing is ideal for applications requiring moisture sealing,
mechanical protection and strain relief.
The adhesive layer is compatible with typical wire insulation and is intended for
moisture sealing and insulation of automotive, RV, truck, trailer, tractor, heavy
equipment and marine wire splices, in-line components, fusible links and terminals.
Shrink Ratio
3M SMS tubing has a 4:1 shrink ratio. When fully recovered, the tubing will shrink
25% of its original diameter. The recovered wall thickness of the tubing is
proportional to the degree of recovery.
The operating temperature range is -55ºC (-67 ºF) to 110ºC (230 ºF), with a
minimum shrink temperature of 121ºC (250 ºF).
