Flexible Shielding

25% Flexi-Boron

Sizing: 12" x 24",  24" x 36", 14.5" x 15", and 6" x 6"

Flexi-Boron has a very high boron concentration (2.32 x 10²² boron atoms/cc) 14.5x15 with 25 weight-percent boron uniformly distributed through each silicone elastomer sheet.  The high boron content provides a thermal neutron attenuation factor of 259 for the standard 1/8" (3.2mm) thickness.  It will withstand temperatures up to 400°F (205°C) without loss of physical or nuclear properties, and is self-extinguishing when exposed to flame.

Flexi-Boron's flexible sheet material is useful for shielding irregular shapes such as cylinders.  It can also be bent in a radius as small as 1/4" (6.4mm).  Shieldwerx stocks several standard sheet sizes including: 1/8" x 12" x 24" (3.2 x 305 x 610mm) and 1/8" x 24" x 36" (3.2 x 610 x 914mm).  Other rectangular sizes and thicknesses are available. SWX-238 is also available in cylinders of custom diameters and wall thicknesses.  Though typically pre-cast, type 238 can be shipped as a field castable Mix Kit, as pictured with the Castable Shielding products.
