MDT Tubing Medium-Duty, Polyolefin Data Sheet Product Description TM 3M MDT Tubing offers increased flexibility in combination with excellent abrasion, corrosion and environmental resistance properties and meets MILDTL-23053/15, Class 2. Uncoated product (without sealant) is available on special order. 3M MDT medium-duty tubing is designed to provide reliable performance as well as excellent mechanical and environmental protection. These flame-retardant products combine the important advantages of easy handling and installation with maximum operating reliability and system protection. MDT comes with a factory-applied sealant. This sealant is a heat-activated thermoplastic material that remains soft and flexible over long periods under adverse environmental conditions. During heating the sealant softens, bonds to underlying surfaces and fills small voids that might be present. When cool, the sealant forms a barrier against water, moisture, dirt and other environmental contaminants. Typical Applications MDT Tubing installs easily and has shrink ratios to accommodate effective insulating and sealing over large transitions, splices and battery cables. Standard Colors All sizes available in black. MDT-0400, -0800 and -1100 are also available in red. Standard Packaging Four-foot lengths. Other lengths are available subject to special quotation.
