Smart Polymer Applications Entering Mainstream Markets
By Don Rosato
Properties inherent in shape memory polymers and other smart polymers have the potential to be game-changers across many industries. In the automotive field, these advanced materials may eventually lead to vehicle subsystems that can self-heal in the event of damage, or that can be designed to change color or appearance. In the medical field, smart polymers are being chemically formulated to sense specific environmental changes in biological systems and adjust in a predictable manner.

Eco-Molding: More Power for Less Energy
Plastics Engineering
For years injection molding machine makers have touted savings of 30 percent, 50 percent, and even more in energy cost. But OEMs typically calculate energy savings by comparing new efficient machine functions to old-fashioned hydraulics in which standard induction electric motors run at constant RPM. These power one or more hydraulic pumps, running constantly, even when the machine is idling. The big energy savings come from reducing that unnecessary motion by adding servo motors to hydraulic pumps and variable frequency drives to electric motors, so they only turn when needed.

  • Recycling Equipment Makers to Show Technology for Sustainability
    Plastics News
    Never has recycling been more at the forefront of the world’s consciousness, and that’s certainly is the case for plastics recovery and recycling. While moms and pops and kids do their part by diverting their recyclables from the trash, and waste management companies do their part by collecting and sorting those materials, the entire recycling community is interdependent on each portion of the process.

    New Carbon Progress from BASF and SGL
    EcoComposites
    SGL and BASF have successfully completed a joint project to enhance the cost-effectiveness of manufacturing carbon fiber/thermoplastic composites in injection procedures – specifically thermoplastic resin transfer and reaction injection molding. The resulting composite is based on a reactive polyamide system and compatible with carbon fibers. A carbon-fiber surfacing agent – or sizing – specially designed for the matrix system, as well as tailored thermoplastic reactive systems means that lightweight structural components for the automotive industry can now be manufactured quickly and easily.

    Weak US Factory Data Suggest Softer Economic Growth
    Reuters
    U.S. manufacturing output fell in February for the third straight month as the production of automobiles and a range of goods tumbled, the latest indication of slower economic growth in the first quarter. Factory production slipped 0.2 percent after declining 0.3 percent in January, the Federal Reserve said on Monday.

    Polyurethane Adhesive Can Replace Epoxies
    Engineering Materials
    Polytec PU 1000 is a single-part adhesive which cures quickly at room temperature to a flexible, electrically conductive polymer. It can replace traditional, rigid epoxies, says Intertronics, which require thermal processing. The resulting production efficiencies enable new applications where pliability and conductivity is important.

    Results of Michigan Study into Biodegradation-Promoting Additives Evoke Incensed Response
    Plastics Today
    It was not to be expected that the results of the study performed at Michigan State University into the effect of biodegradation-promoting additives on the biodegradation of PE and PET would be greeted with any enthusiasm by the manufacturers of these additives. The Michigan researchers, who evaluated biodegradation in compost, anaerobic digestion, and soil burial environments, were singularly unimpressed by the performance of the tested additives. As they wrote: "None of the five different additives tested significantly increased biodegradation in any of these environments. Thus, no evidence was found that these additives promote and/or enhance biodegradation of PE or PET polymers."

    UC Berkeley Showcases World's 1st 3-D-Printed Cement Structure
    Global Post
    Researchers with University of California at Berkeley have unveiled the first-ever structure made solely from printed cement pieces, so as to demonstrate the capacity and versatility of 3-D printers. The research team, led by associate architecture professor Ronald Rael at Berkeley's Environmental Design (CED) College, created the small pavilion known as "Bloom" in one year, to prove that this type of technology can go a long way. The structure was built by printing 840 bricks of cement and then assembled them together.

    PTFE-Modified Compounds Exhibit Wear Resistance Under High Loads
    Thomasnet
    Comprising polymers lubricated with PTFE formulation, LUVOCOM XTF series provides low coefficient of friction while preserving mechanical performance. Benefits include short running-in behavior at start-up. Minimizing deposition in tool cavities, mechanical properties result in PTFE not separating from polymer during injection molding process. Currently available versions include LUVOCOM 1105-9098/XTF and 1105-9182/XTF, which are based on PEEK (polyetheretherketone) polymer.

    Polymers Designed for Protection
    Phys.org
    Today's soldiers rely on polymers as part of their protective systems. Polymers are molecular chains that can vary from a few linked monomers to millions of chemical units. With highly tunable properties and versatile processing they have become ubiquitous in use. In the defense community polymer fibers are particularly well known, especially polyamide fibers such as Kevlar and Nomex and polyethylene fibers such as Dyneema and Spectra. By combining good ballistic protection with a minimal weight penalty these materials have become commonplace in Soldier protection systems.

    Prices Fall for PET, Nylon and PC
    Plastics News
    Lower feedstock costs have driven down North American prices for PET bottle resin, nylon 6 and 6/6 and polycarbonate since Jan. 1. Regional PET bottle resin prices fell an average of 5 cents per pound in January and are believed to have been flat in February. The January drop is shown on this week’s Plastics News resin pricing chart. Prices for the material already had fallen an average of 11 cents per pound in the last two months of 2014 as prices for oil-based feedstocks fell and carbonated soft drink demand continued to decline.

    Plastics News
    A new injectable polymer developed by researchers at the University of Washington in Seattle could help strengthen blood clots and save lives. PolySTAT can be injected into the patient on site to stop bleeding before reaching a full medical team at a hospital or trauma center. In a study on rats, researchers at UW found it saved 100 percent of animals with fatal injuries to the femoral artery. In comparison, just 20 percent of rats treated with a natural protein to help blood clot survived.
