Many of the plastics on display at the recent NPE2012 show in Orlando, Fla., were sustainable in one way or another, and their manufacturers' booths were highly visible in the show's Emerging Technology pavilions. Some of them, like BASF's Ecovio, are compostable or recyclable at the end-product stage, some are made from recycled materials, like SABIC's Xenoy iQ or Stryrolution's PCR materials, and some are constructed of bio-materials, such as Altuglas' Rnew.

Compared to other Plexiglas formulations, bio-based Rnew-maker Altuglas says it has greater melt flow and lower processing temperatures. Its properties, including impact resistance and chemical resistance, can be tailored, and it can be first extruded, then thermoformed with a high degree of detail, as shown here.

Hopefully, this film is available to be applied in a large scale application. Many large scale farm plants have been genetically engineered to specifically resist herbicides (ie Round Up Ready Corn). This allows the farmers to spray the entire field to kill weeds while retaining their cash crop. If this film allows for the farmer to reduce the amount of herbicide and geneticallly engineered seed, it would only be a net gain to consumers.
Tim, this material is specifically targeted for large-scale agricultural applications, as an alternative to poisonous sprays like Roundup and genetically modified (GM) crops. So is black petro-based plastic, but this material has even more benefits, since it can be plowed under, saving time and cost of removal, and saving the damage done if not removed.
This grab-bag of new fasteners and adhesives work with a range of materials they can attach to, as well as a wide variety of applications. Several are for use in consumer applications, such as wearables or other compact electronic assemblies, and some of the adhesives have extended service temperature ranges and cure at room temperature.
Several of the new and noteworthy 3D printers in this slideshow are breaking some boundaries in build volume, new metals printing techniques, or working with high-profile development partners to ensure very high-quality parts and controls.
United Launch Alliance will fly 3D-printed flight hardeware parts on its rockets starting next year with the Atlas V. The company's Vulcan next-gen launch vehicle will have more than 100 production parts made with 3D printing. The main driver? Parts consolidation and 57% lower production costs.
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.
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.
