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.
At the JEC Europe 2015 composites show in Paris last month, makers of composite materials, software, and process equipment showed off their latest innovations. This year's show saw some announcements related to automotive applications, but many of the improvements came in the world of aerospace.
The DuPont-sponsored Plastics Industry Trends survey shows engineers want improved performance in a broad range of plastics and better recycling technology. These concerns top even processing enhancements that improve productivity.
Plastics leader SABIC recently announced a global initiative to help its customers take advantage of additive manufacturing (AM) and also advance 3D printing (3DP) technologies in several application areas. The company's plans go way beyond materials, and also include design, processing, and part performance.
A theme that was reflected in several ways at NPE 2015 was the use of 3D printing to assist in, or improve on, injection molding, as well as improvements in 3D printing materials and processes that are making better functional prototypes and end-use parts.
