3MTM Heat Shrink Tubing SMS Adhesive-Lined, 4:1, Semi-Rigid, Polyolefin for the Automotive Industry Data Sheet May 2010 Description 3MTM 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. SMS tubing does not degrade when exposed to automotive and marine environments and is not affected by severe vibration, extreme temperature changes, moisture or automotive fluids. Features All-Weather, Heat-Shrinkable, Dual Wall, Polyolefin Tubing for Automotive Wire Harnesses * * Applications Semi-rigid polyolefin Provides excellent strain relief * Functional over wide temperature range * Puncture resistant * Resistant to salt water, automotive fluids and corrosive chemicals * Fire retardant Semi-rigid 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 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 -55C (-67 F) to 110C (230 F), with a minimum shrink temperature of 121C (250 F). 1 of 3 3 3MTM Heat Shrink Tubing SMS Standard Sizes and Dimensions Typical Properties Ordering Size Maximum Expanded I.D.
