The best hope for new bioplastics is to find niche applications where they fill a technical need. One great new example comes out of Cornell University, where research set up a company called Novomer to develop plastics made from carbon dioxide and cirtus fruits. Aliphatic polycarbonates (APCs) made from the process are biodegradable, biocompatible, are optically clear and provide high oxygen and water barrier. They’re also quite pricey – say $50 a pound an up.
Novomer today announced its first commercial product — NB-180, a poly(propylene carbonate) (PPC) sacrificial binder that burns cleaner, more uniformly and at lower temperatures than currently available products. Sacrificial binders provide mechanical strength to ensure uniform consistency, solidification or adhesion during manufacturing processes. Application areas are extremely broad and include advanced ceramics, microelectronics, nanotechnology, metal brazing and fuel cells. It’s aimed at assembly of micro- and nano-scale devices.
Fox Holt, product manager for Novomer says there are no plans yet to use the material as a sacrificial binder in powder injection molding – a mass market where it could really achieve some volume.
How can automakers, aerospace contractors, and other OEMs get new metal alloys that are stronger, harder, and can survive ever higher temperatures? One way is to redesign their crystalline structures at the nanoscale and microscale.
Although a lot of the excitement about 3D printing and additive manufacturing surrounds its ability to make end-products and functional prototypes, some often ignored applications are the big improvements that can come by using it for tooling, jigs, and fixtures.
A fun and informative tour you can attend at the upcoming Design & Manufacturing Minneapolis, MD&M Minneapolis, and other events there, is the Materials Innovation Tour on Wednesday afternoon. I'll be leading it.
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.
