NST Tubing Modified Chlorinated Polyolefin (Neoprene(R)) Data Sheet Product Description TM 3M NST Tubing provides superior cutthrough and abrasion resistance and is unaffected by common fluids and solvents. Resistance to oils is excellent. The tubing maintains flexibility at low temperatures and can be readily marked by hot-stamp and print-wheel methods. When heated in excess of 135C (275F) NST Tubing rapidly shrinks to a skintight fit. NSTis rated for continuous operation from -70C (-94F) to 121C (250F). Typical Applications Standard Color NST Tubing is recommended for applications requiring a tough, highly flexible covering. It is particularly useful for fabrication and repair of flexible harnesses and wire bundles and for covering hydraulic couplings. Its superior mechanical properties and broad operating temperature range make it an ideal choice for jacketing cable harnesses and custom-made cables that must operate in severe environmental conditions. Black. Shrink Ratio NST Tubing has a 2:1 shrink ratio. When freely recovered, the tubing will shrink to 50% of its as-supplied internal diameter. The recovered wall thickness is proportional to the degree of recovery. Standard Packaging Spools. Ordering Information Order NSTTubing by product name, size equivalent to the expanded inside diameter, package type and color. Always order the largest size that will shink snugly over the component to be covered. When ordering NST Tubing, please indicate the applicable specification required. Example: NST, 3/16", spools, black. Typical Properties Standard Sizes and Dimensions Ordering Size Expanded I.D. (Minimum) in. (mm) Recovered I.D. (Maximum) in.
