Nanosheets made from poly-L-lactic acid (PLLA) show tremendous potential for use in wound-dressing applications. The materials can cling to the body's most difficult-to-protect contours and keep bacteria at bay. 

Hydraulic seals tested on Arburg machines

The reliability of a hydraulic injection molding machine often comes down to how well the seals perform. They must endure literally millions of molding cycles. Leading machine builder Arburg GmbH (Loßburg, Germany) turns to Trelleborg Sealing Solutions (Stuttgart, Germany) for the polytetrafluoroethylene- (PTFE) based seals employed in its machines, which incidentally are also molded by Trelleborg Sealing Solutions on Arburg machines.

Sony to market proprietary recycled plastic material to third parties

When Sony resolved to do something about reducing the amount of virgin, oil-based plastics it used to manufacture its products, it soon became apparent that the company was not one for half measures. Next to reducing the amount of plastic used and introducing recycled plastic in new products, Sony decided to develop its own recycled plastic. The result was SoRPlas: Sustainable Oriented Recycled Plastic.

Originally made by Sony for Sony, the material has proved such a success that the company has now decided to sell it to external parties.

Making the case for waste-to-energy

For the past two decades, I've heard numerous plastics industry scientists and engineers make the case for burning trash - specifically the "trash" that contains extremely BTU value. But instead of getting the real value out of post-consumer plastics through waste-to-energy (WTE), we spend a tremendous amount of energy (most of it coming from fossil fuels) to recycle plastics, paper, glass and other commodities. The U.S. is behind the times on this issue.

Lightweighting and use of lightweight structural materials will be the key enabler in realizing 2017-2025 CAFE (Corporate Average Fuel Economy) standards according to 49 percent of the respondents in an annual survey sponsored by DuPont Automotive (Troy, MI). 

Plastic pipe demand expected to outpace all other materials

By PlasticsToday Staff
Published: August 7th, 2014

The U.S. demand for pipe is expected to rise 7.3% per year to $63.5 billion in 2018, according to a report from The Freedonia Group. Gains will be driven by strong growth in crude oil and natural gas activity, as pipe is used extensively in drilling and oil and gas pipeline applications. Demand will also be supported by a projected rebound in building construction expenditures.

As lightweighting of vehicles to meet new regulations for fuel economy becomes more pervasive, OEMs and suppliers are collaborating on the development of new thermoplastics for use in various structural applications. Zwick/Roell AG, a global supplier of material and component testing systems, recently introduced a new generation of equipment that improves the accuracy, versatility and flexibility in the testing of thermoplastics for automotive applications.

Molded nanopillars could be line of defense against counterfeit drugs and devices

By Norbert Sparrow
Published: August 6th, 2014

Counterfeit drugs reportedly kill more than 700,000 people annually, and there have been reports of a rise in bogus medical devices, as well. To combat this alarming trend, researchers at the University of Michigan and in South Korea have developed a technique that reveals a hidden image in labels when they are breathed on, allowing users to authenticate a product.
