Borotron® is a family of polyethylene shapes enhanced with varying degrees of elemental boron for use as a medical and industrial shielding material to attenuate and absorb neutron radiation. This easily fabricated polymer material also offers designers greater durability and function over a wider range of temperatures than traditional materials. While essentially any type of PE is suitable for shielding against high energy neutron radiation, borated PE moderates both fast neutrons and lower energy thermal neutrons.
