Borotron™ HM015 shapes are made from high molecular weight polyethylene that is enhanced with 1.5% elemental boron. The boron enhancement makes this grade suitable for use in medical and nuclear shielding applications. The high hydrogen content of HMW-PE allows the material to absorb thermal neutrons, which are then absorbed by the added boron compound. For these reasons, Borotron™ HM015 HMW-PE components are prevalent in nuclear and medical technology.
