New polymer additive could revolutionize plastics recycling

Only 2 percent of the 78 million tons of manufactured plastics are currently recycled into similar products because polyethylene (PE) and polypropylene (PP), which account for two-thirds of the world's plastics, have different chemical structures and cannot be efficiently repurposed together. That could all change with a new discovery.

Melt Flow Rate Testing–Part 1

Though often criticized, MFR is a very good gauge of the relative average molecular weight of the polymer. Since molecular weight (MW) is the driving force behind performance in polymers, it turns out to be a very useful number.

Plastics: Update and New Developments in the Plastics Industry

We’ve come a long way from the black Bakelite phones and radio cases. In fact, your new coffee cup may actually be made from corn-based plastics. While the origins of man-made polymers can be traced to the nineteenth century, the development of novel plastic materials and break-through applications continue at an intense pace.

Producing Biodegradable Plastic Just Got Cheaper and Greener

Biodegradable drinking cups or vegetable wrapping foil: the bioplastic known as polylactic acid (PLA) is already a part of our everyday lives. And yet, PLA is not yet considered a full alternative to traditional petroleum-based plastics, as it is costly to produce. Researchers from the KU Leuven Centre for Surface Chemistry and Catalysis now present a way to make the PLA production process more simple and waste-free.

RECYCLING: Recycling’s ‘Vision’ of the Future

Plastic recycling has come a long way over the last few decades. Expanded collection efforts, increased demand for reclaimed material, and technology advances have combined to allow greater recovery of materials. While technology innovation spans a wide range of processes—from shredding through compounding and extrusion—one category that is receiving more attention and credit for growing recovery opportunities is automated sorting technology.

New Survey Details 3D Printing’s Impact On Manufacturing

3D printing is often referred to as a ‘revolution’ and ‘game-changer,’ but where is it heading? A new report from Stratasys, Minneapolis, aims to answer that question. The report, “3D Printing’s Imminent Impact on Manufacturing,” is based on an independent survey of 700 designers, engineers and executives – 40% of whom are employed by companies with over $50 million in revenue. In addition, respondents work for companies that are committed to using 3D printing.
