I’ve heard of several new plastics that make excellent metal replacements. But concrete? That’s a first for me. A hydrogen-rich polymer loaded with boron actually can replace concrete as neutron-shielding material in nuclear power plants or nuclear submarines. The new Quadrant EPP material is currently available in machinable 1-inch x 48-inch x 96-inch plates. Borotron HD050 is a high-density polyethylene (HDPE) enhanced with 5 percent elemental boron to provide extra shielding against neutron radiation. The combination of boron within a matrix of HDPE, a naturally hydrogen-rich material, targets nuclear shielding applications. Hydrogen-rich materials attenuate neutrons extremely well and boron has an affinity for absorbing thermalized neutrons. Potential uses include shielding for radiation therapy rooms, where the product in plate form is integrated into the wall structure. Other application areas include nuclear research centers, nuclear power plants, power generation areas in nuclear submarines, production areas for nuclear detection devices and the equipment itself, and spacecraft exposed to radiation. Borotron HD050 plate is lighter than some other neutron shielding materials such as concrete, and easier to work with in construction than other options including water. The formulation was engineered by Quadrant Engineering Plastic Products (Quadrant EPP).
Two new technologies from Stratasys, created in partnership with Boeing, Ford, and Siemens, will bring accurate, repeatable manufacturing of very large thermoplastic end products, and much bigger composite parts, onto the factory floor for industries including automotive and aerospace.
These new 3D-printing technologies and printers include some that are truly boundary-breaking: a sophisticated new sub-$10,000, 10-plus materials bioprinter, the first industrial-strength silicone 3D-printing service, and a clever twist on 3D printing and thermoforming for making high-quality realistic models.
