King Plasti-Shield® Borated Polyethylene

King Plasti-Shield® has been used as medical and industrial neutron shielding for more than 25 years. It is a light-weight, cost-effective and easily fabricated solution for a wide variety of neutron-shielding needs. Compared to paraffin-based products, King Plasti-Shield sheets are durable and perform well in a wider range of temperatures.

With 5% boron by weight and a distinctive purple color, King Plasti-Shield Industrial Grade is effective in medical and other applications requiring attenuation of thermal neutrons.

Grade II (yellow, 1% boron) and Grade III (red, 2% boron) are used as neutron shielding in the construction and repair of US Navy ships. These products are manufactured to MIL-P-23536, Rev. A. Certification and testing is available to meet MIL-Spec. requirements

Grades: - Industrial Grade (purple, 5%* Boron by Weight) W - Grade III (red, 2%* Boron by Weight) W - Grade II (yellow, 1%* Boron by Weight) W - Virgin Polyethylene (natural color)

Popular Applications: - Medical vaults and doors for linear particle accelerators and other radiation applications, research applications, nuclear reactors and construction of nuclear-powered vessels.
