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.
This year, Design News is getting a head start on the Fourth of July celebration. In honor of our country and its legacy of engineering innovation -- in all of its forms -- we are taking you on an alphabetical tour through all 50 states to showcase interesting engineering breakthroughs and historically significant events.
Earlier this year paralyzed IndyCar drive Sam Schmidt did the seemingly impossible -- opening the qualifying rounds at Indy by driving a modified Corvette C7 Stingray around the Indianapolis Motor Speedway.
