B2(3X) - Colored Flexible, 3:1 Ratio - Spooled

  • Category: Heat Shrink Tubing
  • Brand: Sumitomo

Colored Flexible Polyolefin, 3 to 1 Ratio, for clear see product A2(3X)

SUMITUBE B2(3X) is a very flexible, flame-retarded, heat-shrinkable polyolefin tubing. B2(3X) is overexpanded to have a recovery ratio of 3 to 1, as opposed to the normal 2 to 1 recovery. B2(3X) is recognized by UL under Subject 224 as 125ºC 600V with a VW-1 rating. SUMITUBE B2(3X) meets the material and functional properties of AMS-DTL-23053/5, Classes 1 & 3, with exception to dimensions. B2(3X) is recommended for use in general purpose applications for protection of components in light wire harness assemblies. It can be used where oversized sub-components prevent the use of a standard heat shrinkable tubing. It can also provide the user with better economies, as one size tubing can often replace 2 standard 2:1 expanded tubing sizes, thereby reducing inventories.

1) SUMITUBE® B2(3X) is a very flexible, flame- retarded, heat-shrinkable polyolefin tubing. B2(3X) is overexpanded to have a recovery ratio of 3 to 1, as opposed to the normal 2 to 1 recovery. B2(3X) is recognized by UL under Subject 224 as 125ºC600V with a VW-1 rating.

2) SUMITUBE® B2(3X) meets the material and functional properties of AMS-DTL-23053/5, Classes 1 & 3, with exception to dimensions.

3) B2(3X) has a low recovery temperature of 90oC.

4) B2(3X) has an operating temperature range of -55oC to +135oC with up to 200oC for short duration.

5) B2(3X) is recommended for use in general purpose applications for protection of components in light wire harness assemblies. It can be used where oversized sub-components prevent the use of a standard heat shrinkable tubing. It can also provide the user with better economies, as one size tubing can often replace 2 standard 2:1 expanded tubing sizes, thereby reducing inventories.
