3M Tape, Film, Grey, 0.5Inch, 36Yard; Tape Type 3M 5490 1/2" X 36 YD

3M,Ñ¢ PTFE Extruded Film Tape (part number 03P9646) features a gray extruded polytetrafluoroethylene (PTFE) backing with a silicone adhesive. The tape measures 0.5 inches in width and has a total roll length of 36 yards (32.9 meters). It has a total thickness of 3.7 mils (0.09 mm) and a backing thickness of 2.0 mils (0.05 mm). This tape exhibits a temperature use range from -65°F to 500°F (-54°C to 260°C) and provides good adhesion to steel, with a typical adhesion strength of 27 oz/in (29 N/100 mm). It is designed to resist curling during unwind and offers a smooth surface when applied. The tape is suitable for applications requiring a low coefficient of friction and chemical resistance, although it is not recommended for use with organic solvents due to the silicone adhesive's vulnerability to such substances. Engineers may consider this tape for applications such as providing an easy-release surface on rollers and plates, sealing and masking, or wrapping rubber nip rollers in hot polyethylene extrusion machines. Proper storage conditions are recommended to maintain performance, with a shelf life of 24 months from the date of manufacture.
