Almost any material can be metalized and coated without solvents in an interesting new technology from Germany that will be on display at K 2010. Materials treated by patented “plasmadust” technology from Reinhausen Plasma GmbH include plastics, metals, silicon disks, glass, foil or even paper.
Using atmospheric pressure, plasma technology is combined with micro- or nanopowders to allow direct-coating, VOC-free processes. A low-temperature (120 - 250 C) plasma gas is generated with a pulsed arcing gas discharge. The coating of a substrate of one square meter requires 1/10 to 1/100 of the power required by thermal plasma injection processes.
Among the applications are plasma and laser sintering, solar cell wafer metallization, and the manufacturing of thin-film batteries and fuel cells.
A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
Although bio-based polymers face challenges from petroleum-based polymers, in certain markets they can displace the petro-based incumbents. Here are six new bio-based and renewable plastics for a variety of applications.
BASF has developed tools and initiatives to help engineers use more of its renewable materials in their designs, more effectively, as well as to build parts using them with more predictable performance.
Just in time for Earth Day, chemicals leader Bayer MaterialScience reported from the UTECH Europe 2015 polyurethane show on programs and applications using its materials to help reduce energy usage. The company also gave an update on its CO2-based PU as that eco-friendly material comes closer to production.
A slew of announcements about new materials and design concepts for transportation have come out of several trade shows focusing on plastics, aircraft interiors, heavy trucks, and automotive engineering. A few more announcements have come independent of any trade shows, maybe just because it's spring.
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.
