Where To Buy

King Plasti-Shield® is a borated polyethylene neutron shielding material. It is the product of a proprietary process called K-Stran™, the most advanced manufacturing process for superior flatness and consistency of 1” thick. Custom sheets, blocks and slabs can be made as a special order in the compression mold or extrusion mold. King Plasti-Shield® has a smooth finish on both sides of the sheet. It is made with 5% boron by weight and our trademark purple color. King Plasti-Shield® is an effective shielding material 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. The polymer sheet never needs painting or refinishing, works like wood and it is easy to fabricate using common woodworking tools and techniques.
