Introduced six years ago, a flexible polyphenylene oxide/polystyrene
polymer is steadily making
progress as a PVC replacement in wiring in major applications such as cars,
medical diagnostic equipment and telecommunications gear.
There is about a mile of wiring in a typical car today
and more than half of it is coated with PVC, a material on some environmental
Delphi is replacing PVC with the Sabic Innovative
PPO/PS materials in ultra-thin-wall cable insulation that reduces weight by up
to 25 percent and reduces mass to allow more vehicle content in the same space.
"The new resin that Sabic Innovative Plastics developed
for Delphi has enabled us to go to market with an automotive cable that not
only supports environmental initiatives and meets our customer's needs for a
better alternative to current offerings, but also provides inherent advantages
in mass and bundle size," says Lynn Long, business line manager for Specialty
Wiring, Delphi Packard.
Samtec, a manufacturer of high-performance, precision
data cable based in New Albany, IN, is now producing a new ribbonized data rate
cable assembly with a coating of 0.005 inch for a Computed Tomography (CT)
When extruding a dual-material layer over a solid center
conductor, pinholes and breakaways occurred, and the solution was hard to strip
"Due to our difficulties with this dual-material approach
and our desire to eliminate chlorine, we sought a better alternative," says Ian
Smethurst, business development manager for Samtec. "Our requirements also
included the ability to produce very thin coatings, flame retardance that would
comply with requirements for non-halogenated parts, and ease of stripping and
prepping. From a cost standpoint, we wanted to be able to run the replacement
coating material on our existing extrusion and ribbonizing equipment."
Most potential replacements were highly filled,
precluding use of the company's extrusion equipment. Instead, the company
turned to flexible Noryl.
LTK Industries, a Hong Kong-based wire and cable OEM, is
using flexible Noryl in appliance wiring material applications used in consumer
The OEM says that flexible PPO resin surpasses other
non-halogenated materials, including thermoplastic elastomers (TPEs) and
polyethylene (PE), with an excellent balance of mechanical properties,
flexibility and color retention. It is also recyclable in the original
extrusion manufacturing process while retaining a high level of mechanical
performance. LTK required high-end performance, including excellent tensile
strength and elongation, flexibility, heat aging, cold bending and aesthetics.
Noryl is widely used in japan for power cord applications
using three Flexible Noryl resin grades.
From home enthusiasts to workers on the manufacturing floor, everyone's imagination is captured by the potential of 3D printing. Prototyping, spare parts creation, art delivery, human organ creation, and even mass product production are all being targeted as current and potential uses for the technology.
ABI Research, a firm based in the UK that specializes in analyzing global connectivity and other emerging technologies, estimates there will be 40.9 billion active wirelessly interconnected “things” by 2020. The driving force is the usual suspect: the Internet of Things.
Just in time for Earth Day, chemicals leader Bayer MaterialScience reported from the UTECH Europe 2015 polyurethane show on programs and applications using its materials to help reduce energy usage. The company also gave an update on its CO2-based PU as that eco-friendly material comes closer to production.
Solar and wind energy are becoming more viable as a source of energy on the electric grid. For decades, the major drawback to solar and wind was that they’re temperamental. A cloudy day kills solar and a still day renders the wind turbines useless. Automation tools, however, are providing a path to help these renewables become practical.
In honor of Earth Day, the National Security Agency has launched the STEM Recycling Challenge in Maryland schools to encourage kids to think about where the garbage they throw out every day actually goes. The agency has also introduced “Dunk,” a muscular blue cartoon recycling bin wearing shorts and sneakers.
