DSM, a Dutch materials company, is exhibiting new nylon applications
at K 2010 as part of its ongoing transformation toward higher-performance
The primary development focus is on a nylon that DSM
describes as the first new polymer developed in the 21st century — a material
first designated PA4T and now called Stanyl ForTii. Announced in 2009, Stanyl
ForTii is a halogen-free, flame- retardant, high-temperature polyamide.
The "T" represents terephthalate. "The halogen-free flame
retardants work better in 4/T than in 4/6," Wilfred van Pelt, DSM global technical product manager, said in a briefing with reporters at DSM's Chemelot
production and research site in Geleen, The Netherlands. The chemistry used to
provide flame retardance is proprietary, but Haventh did say it is phosphor
On June 22, DSM inaugurated its new Stanyl ForTii production
unit, which quadruples capacity.
Gart Kostermans, project director Stanyl ForTii of DSM
Engineering Plastics, said, "Stanyl ForTii supports market trends that
call for miniaturization and the convergence of electronic devices. It is our
expectation, based on solid customer programs in hand, that we will utilize
this expansion fully in the very near future."
Stocko Contact, a German
manufacturer of electromechanical components, plans to switch all its SMT
connectors to Stanyl ForTii. Two new series of pin connectors are designed
mainly for use in dishwashers, washing machines, dryers and refrigerators.
The connectors can be assembled with lead-free reflow
soldering, making this the first RAST platform that can be reflow soldered.
RAST is a new connector standard that was developed to avoid
"Stocko is the first
company to introduce SMT RAST solutions with significant cost reduction
compared to previous through-hole solutions," said Michael Degenhardt, design
engineer for connectors at Stocko Contact.
Stanyl ForTii properties include dimensional stability, full
compatibility with lead-free reflow soldering, high stiffness and mechanical
strength at elevated temperatures, and a high melting and glass transition
Stanyl ForTii meets miniaturization requirements for
electronic devices such as cell phones and computers. Potential electronics
applications include memory card connectors, CPU sockets, high-temperature
bobbins, switches or notebook computer memory module connectors. In automotive
markets, the material supports developments in under-the-hood applications for
electrical systems, air/fuel and powertrain components. In the lighting
industry, trials have been conducted for light-emitting diode packages and
modules due to high reflectivity and high temperature stability.
In another application development, FCI, a supplier of
interconnect products, has approved halogen-free V-0 Stanyl ForTii for its FPC
connectors product line of optical disk drives and is currently expanding the
usage on various other connectors and sockets.
Optical disc drives (ODDs) are an integral part of computers
and stand-alone consumer appliances such as CD, DVD or Blu-ray disk drives. A
crucial part of such an optical disc drive is the pickup head, consisting of
the laser, a lens for focusing the laser beam and photodiodes detecting the
light reflected from the surface of the disc. The electrical connection to this
critical component is made by flexible printed circuit (FPC) connectors.
A postcard or post card is a rectangular piece of thick paper or thin cardboard intended for writing and mailing without an envelope. There are novelty exceptions, such as wood postcards, made of thin wood, and copper postcards sold in the Copper Country of the U.S. state of Michigan, and coconut "postcards" from tropical islands.
In some places, it is possible to send them for a lower fee than for a letter. Stamp collectors distinguish between postcards (which require a stamp) and postal cards (which have the postage pre-printed on them). While a postcard is usually printed by a private company, individual or organization, a postal card is issued by the relevant postal authority.
The first Tacoma Narrows Bridge was a Washington State suspension bridge that opened in 1940 and spanned the Tacoma Narrows strait of Puget Sound between Tacoma and the Kitsap Peninsula. It opened to traffic on July 1, 1940, and dramatically collapsed into Puget Sound on November 7, just four months after it opened.
Noting that we now live in an era of “confusion and ill-conceived stuff,” Ammunition design studio founder Robert Brunner, speaking at Gigaom Roadmap, said that by adding connectivity to everything and its mother, we aren't necessarily doing ourselves any favors, with many ‘things’ just fine in their unconnected state.
