There are no revolutions under way in the world of engineering plastics. New materials today target very specific problems. One interesting set of materials from BASF helps to better insulate houses, as shown in a demonstration project in England. Michael Guibault, a marketing manager for BASF’s construction polymers business in North America, says architects can now design buildings that have the energy-efficiency advantages that previously only came with thicker, traditional materials. Here’s how it works: Plastic capsules are filled with a wax that absorbs and then releases energy by melting and solidifying. When used in an astronaut’s spacesuit, a soldier’s uniform, or within an interior plaster or plasterboard wall, the capsules boost the thermal capacity of the material and reduce temperature swings. "Manufacturers of interior building materials can utilize BASF’s Micronal phase-change microcapsules to create new product categories that can give them a competitive advantage," says Guibault.
Last week, the bill for reforming chemical regulation, the TSCA Modernization Act of 2015, passed the House. If it or a similar bill becomes law, the effects on cost and availability of adhesives and plastics incorporating these substances are not yet clear.
The latest crop of coating and sealant materials and devices has impressive credentials. Many are designed for tough environments with broad operating temperature ranges, and they often cure faster, require fewer process steps, and produce less waste.
A new program has been proposed for testing and certify 3D printing filaments for emissions safety. To engineers who've used 3D printers at home this is a no-brainer. It's from a consumer on Kickstarter, and targets use in homes and schools.
For the last 50 years, the Metal Powder Industries Federation (MPIF) has sponsored an awards competition for creative solutions to designing and fabricating near-net-shape parts using powder metal (PM) technologies. Here are the seven Grand Prize winners of the 2015 contest.
Graphene 3D Lab has added graphene to 3DP PLA filament to strengthen the material and add conductivity to prints made with it. The material can be used to 3D print conductive traces embedded in 3D-printed parts for electronics, as well as capacitive touch sensors.
