Teflon

Teflon, a DuPont trademarked product, is a fluoropolymer, and there are three flavors of it now. Let's look at them. One is polytetrafluoroethylene (Teflon-PTFE), which is the stuff cookware is coated with. It's carbon and fluorine. Another is perfluoroalkoxy (Teflon-PFA), and it's used to make tubing and other products. It is largely like PTFE, but has a bit of oxygen in its chemistry. The third is fluorinated ethylene propylene (Teflon-FEP), and its about the same as Teflon PFA, which is to say it's mostly carbon and fluorine with a bit of oxygen. A link is provided to the Wikipedia article on Teflon, and you can link to the other articles from there and look at the chemical structure of a given example of one of the fluoropolymers.

The structural formula for Teflon (polytetrafluoroethylene) is (-CF2-). It consists of a repeating unit of two carbon atoms and two fluorine atoms.

No, it is not recommended to use Teflon tape to seal oxygen fittings. Teflon tape is flammable and can pose a safety hazard when used with oxygen, which is highly reactive and can lead to combustion. It is better to use approved sealants or fittings specifically designed for oxygen systems to ensure safety.

Teflon, also known as polytetrafluoroethylene (PTFE), is made up of carbon and fluorine atoms. It is a synthetic polymer that is heat-resistant, non-stick, and chemically inert, making it commonly used in cookware and industrial applications.

There are both fundamental differences, and relationships between these two gives. Stainless steel is an iron based metal alloy. Teflon is a trademarked synthetic chemical used as a nonstick and lubricating coating, often on metal surfaces.

That depends whether it's pure liquid ammonia, or a liquid ammonia solution of metal ions. The former probably won't react, the latter will certainly react as solutions of that type are reducing enough to reduce aromatic hydrocarbons

Teflon was discovered accidentally by Roy Plunkett in April 6, 1938 while

experimenting with synthesizing new types of refrigerant gas when he accidentally produced Teflon.

The chemical formula of Teflon is (C2F4)n, where n represents the number of repeating units in the polymer chain.

The monomer for Teflon is tetrafluoroethylene, which is a colorless gas and a derivative of ethylene. When polymerized, it forms the polymer polytetrafluoroethylene (PTFE), which is commonly known as Teflon.

Teflon is a plastic, also known as Polytetrafluoroethylene which was discovered in 1938, is used as coatings on non-stick cookwares. Teflon has a high melting point unlike many other plastics and does not stick to any food material. This makes cooking effective and cleaning of the pan easy.

In 1938, DuPont scientist Dr. Roy Plunkett discovered Teflon entirely by accident while trying to synthesize a new refrigerant gas.

Plunkett had made & stored a hundred pounds of tetrafluoroethylene (TFE) gas in metal cans with valve releases for easy access. The cans were in turn set on dry ice to keep them cool and liquefied.

As the story goes, one of the cylinders failed to discharge the liquid TFE when the valve was opened. Throwing caution to the wind, Plunkett & his assistant Jack Rebok sawed open the cylinder to find its contents had polymerized. The once liquid TFE had solidified into a white powder.

Dr. Plunkett immediately began testing & trying to replicate the substance now known as polytetrafluoroethylene (PTFE). He received US Patent 2230654 for Tetrafluoroethelyne Polymers in 1941.

the answer to the question when was teflon first made was by a man called.. i cant remember now hang on ill think of it in a sec just keep reading this cos ull find the answer in a min and it was a women who mad it not a man actually it was a i dunno lol

The coating on non-stick cookware is made from a liquid "paint" which contains PTFE (polytetrafluoroethlyene) fluoropolymer and sometimes other fluoropolymers. The final cookware coating is a dried, durable non-stick material which delivers the easy clean and non-stick performance that you expect from your cookware coated with Teflon® non-stick.

While there are Teflon lubricants, Teflon (PTFE) thread seal tape is most definitely for sealing threads. There are relevant standards for these and they are UL listed for such use. Typically for propane & natural gas you would want to use yellow thread seal tape. It is thicker than the standard white. I prefer it over "pipe dope" as it does not harden up with time, and it is guaranteed to have even coverage. In addition to it's ability to seal, the lubricating effects of the tape allow easier tightening of joints, further reducing the liklihood of a leak.

Yes it is. If it gets in your food and you ingest it, it will just pass through your digestive tract without any toxic effects. It's not absorbable. However, it is recommended that you buy new pots and pans as soon as possible (speaking from a wear-and-tear point of view).

They can be aluminium, steel, iron, stainless steel, the 'Teflon' is a non stick coating covering the cooking surface of the base metal.

Sure

With a wrench

At high temperatures cookware coated with Teflon and other non-stick surfaces can break apart and emits toxic particles and gases. The fumes can sick people, but pet birds are even more sensitive. In cases of "Teflon toxicosis," as the bird poisonings are called, the lungs of exposed birds hemorrhage and fill with blood, leading to suffocation. DuPont studies show that the fumes can also sicken people, a condition called "polymer fume fever." The government has not assessed human health risks or the incidence of polymer fume fever from kitchen exposures to these particles and gases when pans are overheated.

Non-stick coatings can contain residues of PFOA (perfluorooctanoate), a chemical used to make Teflon and a breakdown product of stain- and grease-proof coatings on carpet, clothing and food packaging. PFOA is found in the bodies of nearly all Americans. It is a likely human carcinogen; it also has a variety of metabolic developmental, reproductive, endocrine, and neurobiological health effects. Many manufacturers of non-stick cookware have committed to eliminating PFOA residues from non-stick coatings. Available data suggest that non-stick pans are not a major source of PFOA in people's bodies. These exposures are more likely to come from stain- and grease-proof coatings on furniture, clothing, and food packaging.

Studies also show that most of the potential health risks from non-stick pans, such as polymer fume fever, come not from PFOA but from other particles and fumes that can come off the pan when it is overheated. While EWG continues to track the changes in manufacturing practices for non-stick cookware, we highly recommend stainless steel and cast iron as great alternatives to non-stick cooking surface.

You should make sure that the pot has cooled. Otherwise the hot pot might not be safe to put in the fridge. Otherwise the Teflon pot will not harm your fridge.

Mr. Know it all

I think you are completely missing the gist of the question....they want to know if its safe to store food in the teflon pot...in other words they want to make sure the teflon, or metal from the pot will not leach into the food, as it WILL with aluminum pots

You are right to ask this question because Teflon nowadays has many imitators using PTFE as the nonstick coating. Look for an oven liner that use Du Pont food grade Teflon as its non-stick surface; it withstands the heat of an oven and wipes clean even if you let it bake on a bit. I saw this stuff online recently, and it had lots of good reviews.

Teflon is mainly used as a non-stick coating inside frying pans.
