The Neutron Shielding Polyethylene (PE) Board market has transformed from a niche radiation protection material segment into a highly specialized engineered polymer solution category catering to nuclear medicine shielding rooms, research reactor infrastructure, radioactive material logistics, and industrial radiography containment systems. In 2024, global production volume of neutron shielding PE boards was estimated at 85,000 to 95,000 metric tons, with China, the United States, South Korea, Germany, and Japan leading manufacturing output. Capacity utilization remained strong at 82–85%, as demand from nuclear facility modernization projects, healthcare radiation diagnostics expansion, and defense sector shielding applications saw consistent year-on-year increases.
