Flomasta PTFE Liquid 50g

Product Information

Because of its extreme non-reactivity and high temperature rating, PTFE is often used as the liner in hose assemblies, expansion joints, and in industrial pipe lines, particularly in applications using acids, alkalis, or other chemicals. Its frictionless qualities allow improved flow of highly viscous liquids, and for uses in applications such as brake hoses.

In optical radiometry, sheets of PTFE are used as measuring heads in spectroradiometers and broadband radiometers (e.g., illuminance meters and UV radiometers) due to PTFE's capability to diffuse a transmitting light nearly perfectly. Moreover, optical properties of PTFE stay constant over a wide range of wavelengths, from UV down to near infrared. In this region, the ratio of its regular transmittance to diffuse transmittance is negligibly small, so light transmitted through a diffuser (PTFE sheet) radiates like Lambert's cosine law. Thus PTFE enables cosinusoidal angular response for a detector measuring the power of optical radiation at a surface, e.g. in solar irradiance measurements.

Polytetrafluoroethylene (PTFE) was accidentally discovered in 1938 by Roy J. Plunkett while he was working in New Jersey for DuPont. As Plunkett attempted to make a new chlorofluorocarbon refrigerant, the tetrafluoroethylene gas in its pressure bottle stopped flowing before the bottle's weight had dropped to the point signaling "empty". Since Plunkett was measuring the amount of gas used by weighing the bottle, he became curious as to the source of the weight, and finally resorted to sawing the bottle apart. He found the bottle's interior coated with a waxy white material that was oddly slippery. Analysis showed that it was polymerized perfluoroethylene, with the iron from the inside of the container having acted as a catalyst at high pressure. [4] Kinetic Chemicals patented the new fluorinated plastic (analogous to the already known polyethylene) in 1941, [5] and registered the Teflon trademark in 1945.

It is notable for its extremely low coefficient of friction, its hydrophobia (which serves to inhibit rust), and for the dry film it forms after application, which allows it to resist collecting particles that might otherwise form an abrasive paste.

There is a long list of brands that excel in specific tools, but don’t do so well with others. One company that is fantastic across the board is Screwfix. Most cases of polymer fume fever in humans occur due to smoking PTFE-contaminated tobacco, [64] although cases have occurred in people who have welded near PTFE components. [64] PTFE-coated cookware is unlikely to reach dangerous temperatures with normal use, as meat is usually fried between 204 and 232°C (399 and 450°F), and most cooking oils (except refined safflower and avocado oils) start to smoke before a temperature of 260°C (500°F) is reached. A 1973 study by DuPont's Haskell Laboratory found that a 4-hour exposure to the fumes emitted by PTFE cookware heated to 280°C (536°F) was lethal for parakeets, although that was a higher temperature than the 260°C (500°F) required for fumes from pyrolyzed butter to be lethal to the birds.

Durability

When working at heights, never leave tools lying out in the areas where they could present a hazard to the people below. An animal study conducted in 1955 concluded that it is unlikely that these products would be generated in amounts significant to health at temperatures below 250°C (482°F). [33] Above those temperatures the degradation by-products can be lethal to birds, [62] and can cause flu-like symptoms in humans ( polymer fume fever), [63] although in humans those symptoms disappear within a day or two of being moved to fresh air. [64] PTFE is widely used as a thread seal tape in plumbing applications, largely replacing paste thread dope.
