3MMedium-Wall Heat Shrink Tubing IMCSN Data Sheet November 2017 3M Medium-Wall Heat Shrink Tubing IMCSN is designed to provide reliable Product Description 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. Agency Approvals & For RoHS information, please visit www.3M.com/ROHS Self Certifications Product Features 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. Applications 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. 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. 1 of 5 3M Medium-Wall Heat Shrink Tubing IMCSN Characteristics Property Requirements* Test Results and Test Data Continuous Operating -55C to 110C -55C to 110C Temperature Range Color Black Black Longitudinal Change + 1%, - 10% Pass Low Temperature Flexibility No Cracking Pass (4 hours -55C) Heat Shock No Cracking, Flowing Pass (4 hours 255C) or Dripping 2% Secant Modulus 25,000 psi max. 14,000 psi Color Stability Remain Stable Pass (24 hours 175C) Tensile Strength 1,200 psi min. 2,400 psi Ultimate Elongation 200% min. 475% Dielectric Strength (V/mil) 200 min. 500 1 3 1 4 Volume Resistivity (ohm-cm) 1 0 min. 1 0 *Based on MIL-I-23053/15A Class 2 Fluid Resistance / Minimum tensile strength, 750 psi.
