The Q2-F3X-1/2-01-SS150FT is a highly flexible, flame-retardant polyolefin heat shrink tubing supplied on a 150-foot spool. This tubing features a 3:1 shrink ratio, with a minimum supplied inside diameter of 12.7 mm that reduces to a maximum of 4.0 mm after full recovery. It has a recovered wall thickness of 0.80 mm and is designed to operate in temperatures ranging from -55°C to +135°C, with a minimum shrink temperature of 70°C. With a dielectric strength over 20 kV/mm and a 600V rating, it is ideal for applications requiring robust electrical insulation, strain relief, wire bundling, and corrosion protection, especially over irregular shapes.
