King Plasti-Shield® is an effective shielding material with 5% boron by weight and our trademark purple color to meet all applicable applications for healthcare cancer treatment centers, diagnostic and hospital facilities. Applications include linear accelerators, nuclear or radiation shielding, industrial use, security such as seaports and airport security, nuclear submarines, nuclear power plants, border protection and other applications requiring attenuation of thermal neutrons.

King Plasti-Shield is certified by prime vendors of the U.S. government as the source for Grade II and Grade III neutron shielding material on nuclear submarines and naval warships. Our process, materials, quality programs, sampling, testing, tracing and packaging all meet or exceed military specifications such as MIL-P23536A and EB2562E. We use MIL-STD-45662 for internal calibration system traceable back to NIST.
