Hannifin's Texfluor PTFE tubing is chemical and corrosive resistant and is
available in sizes .010 to 4 inch O.D.
PTFE, in many cases, is used to
replace glass, rubber and stainless steel because of its corrosion resistance. It
is extremely resistant to the most highly corrosive chemicals such as aqua
regina, hydrofluoric acid and hydrogen peroxide. Only molten alkali metals,
such as sodium or potassium, chlorine trifluoride and gaseous fluorine at
elevated temperatures and pressures will attack PTFE chemically. In addition,
there is no solution that will swell or dissolve PTFE at temperatures below
300C/570F. Only at temperatures above 327C/620F, PTFE's crystalline melting
point, will some fluorinated lubricating oils swell PTFE.
Texfluor PTFE tubing is odorless, tasteless, non-wetting and non-leaching. Other
advantages are PTFE's ease in cleaning, anti-stick properties, resistance to
extreme heat and cold and resistance to ultra violet rays. Vibration damping
properties of PTFE are also useful in both sonic and ultrasonic frequencies.
Advertised as the "Most Powerful Tablet Under $100," the Kindle Fire HD 6 was too tempting for the team at iFixit to pass up. Join us to find out if inexpensive means cheap, irreparable, or just down right economical. It's teardown time!
The first photos made with a 3D-printed telescope are here and they're not as fuzzy as you might expect. A team from the University of Sheffield beat NASA to the goal. The photos of the Moon were made with a reflecting telescope that cost the research team £100 to make (about $161 US).
The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
