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).
Materials and assembly methods on exhibit at next week's MD&M West and other co-located shows will include some materials you should see, as well as several new and improved processes. Here's a sampling of what you can expect.
The Food & Drug Administration has approved a 3D-printed, titanium, cranial/craniofacial patient-specific plate implant for use in the US. The implant is 3D printed using Arcam's electron beam melting (EBM) process.
The upcoming MD&M West and co-located shows in Anaheim next month will be host to a huge variety of technologies and special events like the Golden Mousetrap Awards. Here are five reasons for medtech professionals to attend.
Many of the new 3D printers and printing technologies in this slideshow are breaking some boundaries, whether it's build speed, new material types, density and quality of 3D-printed circuit board layers, or build volume in a hybrid printer. We also give some recent market statistics.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
