Greg, I saw a preliminary data sheet, but I don't believe it contained that info, and it's not up on the company's website yet. If you contact them to find out more, please let us know the result.

Good to see these types of polymers being developed.  Any idea of the thicknesses needed for a V0 or 5V UL flammability rating? (which many electronic housings need).

Thermoplastic starch vs. mineral filler

@Ann: Many of the comments from your recent article about soy-based polyurethane foam would apply to this material.  In fact, corn-based PLA is significantly more objectionable in terms of its impacts on the environment and the global food crisis.

Furthermore, if the goal is to increase the strength, stiffness, and heat deflection temperature of injection molded plastics, it's already possible to do so using traditional mineral fillers such as talc and calcium carbonate.

The mechanical properties of these new PLA blends look roughly equivalent to what could be expected from a talc-filled PC/ABS.  The main selling point appears to be the ability to put a USDA "bio-based" label on them.

Of course, the role of the USDA is to expand markets for U.S. agricultural products, which the use of bio-based plastics certainly does.

Latest Analysis
With major product releases coming from big names like Sony, Microsoft, and Samsung, and big investments by companies like Facebook, 2015 could be the year that virtual reality (VR) and augmented reality (AR) finally pop. Here's take a look back at some of the technologies that got us here (for better and worse).
Good engineering designs are those that work in the real world; bad designs are those that don’t. If we agree to set our egos aside and let the real world be our guide, we can resolve nearly any disagreement.
The Industrial Internet of Things is bringing a previously reluctant process industry into the wireless fold. The ability to connect smart sensors to the Internet has spiked the demand for wireless devices in process manufacturing, according to the new study from ARC Advisory Group.
If you’re developing an embedded monitoring and control application, then you’ll want to take note of the upcoming Design News Continuing Education Center class, “Embedded Development Using Microchip Microcontrollers and the CCS C Compiler."
US factory orders for durable goods tumbled 3.4% in December on a big drop in new bookings for commercial aircraft, according to data the Commerce Department released Tuesday.
