B2 - Colored Flexible, 2:1 Ratio - Spooled

  • Category: Heat Shrink Tubing
  • Brand: Sumitomo

Colored Flexible Polyolefin, 2 to 1 Ratio, for clear see product A2.

SUMITUBE B2 is a very flexible, flame-retarded, radiation-crosslinked heat shrinkable polyolefin tubing which meets all of the material and functional requirements of Military Specification AMS-DTL- 23053/5, Class 1 and Class 3. B2 is recommended for use in general purpose applications such as wire marking, color coding, and electrical insulation of light wire harness assemblies. For higher expansion ratio versions see B2(3X), B2(4X), and B2(4XC).
