Product overview


Borated polyethylene is a lightweight, cost-effective neutron shielding material widely used in medical, nuclear, and industrial applications. By incorporating elemental boron into a polyethylene matrix, the material absorbs and attenuates neutron radiation while also reducing gamma-capture dose associated with neutron interactions.


Because the material maintains consistent density, it provides predictable shielding performance across applications. It is available in multiple grades with 1 percent, 2 percent, or 5 percent elemental boron content by weight, allowing projects to select the appropriate formulation based on shielding requirements.


Standard sheets are available in 1 inch by 48 inch by 96 inch dimensions, and the material can also be supplied in blocks, pellets, or slabs. It can be fabricated using conventional woodworking tools. In addition, Ultraray offers CNC machining services to produce custom components for neutron shielding assemblies. Borated polyethylene should be selected and installed as part of a comprehensive radiation protection strategy.
