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.
Conventional wisdom holds that MIT, Cal Tech, and Stanford are three of the country’s best undergraduate engineering schools. Unfortunately, when conventional wisdom visits the topic of best engineering schools, it too often leaves out some of the most distinguished programs that don’t happen to offer PhD-level degrees.
Airbus Defence and Space has 3D printed titanium brackets for communications satellites. The redesigned, one-piece 3D-printed brackets have better thermal resistance than conventionally manufactured parts, can be produced faster, cost 20% less, and save about 1 kg of weight per satellite.
A group of researchers at the Seoul National University have discovered a way to take material from cigarette butts and turn it into a carbon-based material that’s ideal for storing energy and creating a powerful supercapacitor.
