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.
The Beam Store from Suitable Technologies is managed by remote workers from places as diverse as New York and Sydney, Australia. Employees attend to store visitors through Beam Smart Presence Systems (SPSs) from the company. The systems combine mobility and video conferencing and allow people to communicate directly from a remote location via a screen as well as move around as if they are actually in the room.
An MIT research team has invented what they see as a solution to the need for biodegradable 3D-printable materials made from something besides petroleum-based sources: a water-based robotic additive extrusion method that makes objects from biodegradable hydrogel composites.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
