As the container market adds styles, sizes and end-use requirements to products, manufacturers of extrusion blow molding machines are upgrading their systems with a range of technologies to meet evolving process needs and improve
cost-performance benefits. Key features of
recent offerings in shuttle, rotary and reciprocating screw equipment include a growing trend toward all-electric machines in North America; efforts to reduce machine size; greater use of networked
controls to improve molding precision, throughput, and quality; and increased reliance on proprietary design and engineering to fine-tune
system performance, speed product changeover, and, in some cases, improve container design.

Waste plastic to become artificial reefs
Khaleej Times
Share
Artificial reefs made from recycled plastic could be the answer to sustaining marine life along Dubai's coastline, following the success of prototypes implemented in tide-damaged areas in Fujairah. These reefs are to be placed in the ocean, in lieu of the actual coral reefs in the Arabian Gulf that have disappeared during the past decade of construction, land reclamation and natural weather fluctuations. The reefs, a first in the
world, according to its creators, are placed in accordance to the Environment, Health and Safety guidelines in a marine protected area.

Structure and mechanical properties of polymer blends incorporating waste PET
SPE Plastics Research Online
Share
The blending of immiscible (nonmixing) polymers such as polycarbonate and acrylonitrile butadiene styrene—used widely in the automobile industry — is an economically attractive route to developing a mixture that retains the desirable properties of both components. In general, the polymers are
selected based on advantageous properties such as toughness, chemical resistance, and heat stability. However, the so-called mixing rule, which calculates the properties of blends based on a linear average, generally does not hold for immiscible polymers because the components form a two-phase structure, such as, part crystal and part amorphous.

Cottonseed protein makes superabsorbent
composite
SPE Plastics Research Online
Share
Superabsorbent polymers are made of hydrophilic networks of cross-linked polymer strands. Their structure gives them the capacity to absorb and hold large amounts of water, saline solution, or other physiological fluids. Due to their excellent characteristics, SAPs are widely used in disposable diapers, incontinence and feminine hygiene products, hospital products, soil for agriculture and horticulture, food packaging and biomedical applications.

Recycled plastic bottles to become casino uniforms
Reuters
Share
U.S. uniform company Cintas Corp is betting on green for its new line of shirts for casino workers. The company has introduced shirts for the gaming industry that are partly made from recycled plastic bottles. Cintas uses technology that converts plastics into a fiber that can then be woven into fabric. About five plastic bottles are needed to create one shirt, most of
which is still manufactured from traditional polyester.

BPF calls for a 'fair crack of the whip' for plastics
Plastics & Rubber Weekly
Share
Incoming British Plastics Federation president Philip Watkins said he wasn't looking for handouts for the sector, rather he hoped the coalition government gave it a "fair crack of the whip." Discussing the outlook for the sector Watkins, who was elected president of the BPF last month, said the industry's critical mass was being challenged, and this needed addressing.

BPA is indispensible for making plastics
Chemical & Engineering News
Share
Polymer producers are in a pickle. Bisphenol A is a versatile and valuable chemical building block that makers of high-performance plastics don't want to give up. But BPA is under intense scientific scrutiny for being an endocrine disrupter, and consumers are pressuring companies to find alternatives. "In terms of viable alternatives, there have certainly been attempts to displace BPA-based plastics such as polycarbonate and epoxy
resins, but until recently, none were successful," says polymeric materials chemist Daniel F. Schmidt of the University of Massachusetts, Lowell.

Composite materials bridge the divide
European Plastics News
Share
Progress in composites materials and manufacturing means resin-based components are increasingly challenging traditional building materials in bridges. French
R&D center Innobat in Montpellier and Italian pultrusion processor Topglass won the bio-based materials category in the JEC 2011 composites innovation awards in March. This was for development, as part of a Biobat project, of a Biopox 65 pultruded hollow window frame and solid flat profiles made out of 65 percent continuous flax fiber reinforced bio-based epoxide resin. The pultruded profiles have an overall 75 percent bio-based content.

Plastic compounds target lead in radiation shielding
Plastics Today
Share
Lead's time in medical devices is quickly running out and opportunistic plastics suppliers are jumping into the void being left by out-of-favor toxic metal to offer polymer compounds that offer
equivalent radiation shielding. "There's a move afoot to try and remove [lead] from the manufacturing environment because it's hazardous to employees and difficult to dispose of," PolyOne's Larry Johnson said. "There are costs and concerns associated with it, so all and all it's kind of a bad actor, and people are trying to remove it."

Turning plants into plastics: Challenges and opportunities in bioplastics for consumer goods companies

In 1934, Henry Ford, the "industrial genius of modern times," declared to Modern Mechanix magazine that in the future we will be able to grow annually "most of the substances needed in
manufacturing…When that day comes...[c]hemistry will reunite agriculture and industry." While it is too soon to suggest that Mr. Ford's prophecy has been fulfilled, a combination of changing consumer demands, concerns of climate change, and a desire to reduce our reliance on fossil fuels are pushing us ever closer to the day he envisioned.
