SR-350 Tubing Semi-Rigid Polyolefin Data Sheet Product Description 3M SR-350 is a semi-rigid, heatshrinkable tubing that offers superior cutthrough and abrasion-resistance characteristics for optimum mechanical performance. In addition, SR-350 Tubing has excellent electrical-insulation and chemical-resistance properties. SR-350 Tubing meets the requirements of MIL-DTL-23053/6, Class 1 & 2, AMS-3638 and AMS-3639. It is UL Recognized at 600 volts 125°C UL File Nos. E-39100 and E69751 . SR-350 Tubing is rated for continuous operation from to 135°C 275°F and withstands operating temperatures to 300°C 572°F for short periods. Minimum shrink temperature for all SR-350 Tubing is 135°C 275°F . SR-350 Tubing is ideally suited for strain-relief applications, wire marking and protective covering and packaging of delicate components. It is widely used for insulating mechanically weak or damagesusceptible points such as solder joints, wire splices and terminations. Because it holds its expanded “roundness,” SR-350 Tubing is highly recommended for use with automatic feed equipment. The tubing is readily printable by hot-stamp or print-wheel techniques. Shrink Ratio SR-350 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 of the tubing is proportional to the degree of recovery. High expansion-ratio SR-350 Tubing is available subject to factory quotation. Typical Properties Standard Colors SR-350, Class 1 flame retardant black. Special color-coded sizes are available. SR-350, Class 2 non-flame retardant clear. Standard Packaging Four-foot lengths. Cut pieces available subject to factory quotation. Ordering Information Order SR-350 by product name, size equivalent to expanded inside diameter, package type and color.

Product Description
3M SR-350 is a semi-rigid, heatshrinkable tubing that offers superior cutthrough and abrasion-resistance characteristics for optimum mechanical performance. In addition, SR-350 Tubing has excellent electrical-insulation and chemical-resistance properties.

SR-350 Tubing meets the requirements of MIL-DTL-23053/6, Class 1 & 2, AMS-3638 and AMS-3639. It is UL Recognized at 600 volts 125°C UL File Nos. E-39100 and E69751 .
