November 2017
3M™ Medium-Wall Heat Shrink Tubing IMCSN is designed to provide reliable
performance for electrical splices, connections, and terminations, as well as mechanical
and environmental protection. 3M IMCSN tubing is fabricated from cross-linked
polyolefin. The tubing is highly split resistant, and fast-shrinking to provide rapid
installation. The tubing comes standard with a factory-applied adhesive/sealant.

Product Selection
Selecting 3M IMCSN tubing is easy and straightforward. The largest tubing that
provides a tight fit when fully recovered will produce the maximum wall thickness. Final
wall thickness is proportional to the degree of tubing recovery.
Fast and easy installation.
Resists puncture and abrasion damage.
Complete environmental protection.
Versatile, a minimum number of sizes cover the entire range of applications.
Shrink ratio 3:1.
Resist acids and alkalies.
Bonds to a wide variety of substrates.
Reliable and proven.
UV resistant.
Primary electrical insulation for solid dielectric wire and cable rated to 1000 volts.
For indoor, outdoor or overhead use.
Direct buried or submersible.
Insulating secondary splices.
Physical protection and moisture sealing of high-voltage air insulated connectors and
lugs, such as lug connections to bus bars.
• Relocation of service.
• Dig-in repairs.

The tubing must be usable both indoors and outdoors, in overhead, direct-buried, or
submerged applications on cables rated up to 1000 volts. It is not adversely affected by
moisture, mild acids and alkalies, fuels, oils, ozone, or ultraviolet light. It must be compatible
with and adhere to all types of cable jackets, including rubber, plastic, or lead. It must
conform to the requirements of UL 486 D and sections 3.4 and 4.3 of ANSI C119.1 1986.
