Why is Teflon used in cookwares?

Answer 1

* non stick coatings.
* gaseous exchange membranes.
* used as grafts in Bio medical application.
* used in manfacture of Stopcocks,glass fibres,Transformers,Plumbing thread tape,etc...
* used in manfacture of computer mice foot,solid fuel rocket propellents,cells used in spectrometer,containers,magnetic stirrers etc...
*it is also used for making non stick cookwares

Answer 2

Teflon applications:

- teflon is used as a nonstick coating for saucepans and frying pans

- gaskets for high temperature and corrosive solutions in chemical industry

- tubes and tubes fittings for high temperature and corrosive solutions in chemical industry

- teflon wool and foils for sealing valves

- beakers, bottles, pipettes, cylinders, crucibles and others for works in chemical

laboratory with very corrosive acids

- lubricants containing teflon

- electrical insulator

- low friction components

- air filters

- production of gore-tex

- medical implants

etc.

Answer 3

Teflon is made up of a substance called Polytetrafluoroethylene, which is considered to be one of the most slippery substance in existence. Teflon is used as a nonstick chemical used on cookware. When used in high temperature (over 400 degrees Fahrenheit), this chemical has been found to release some highly toxic chemicals such as PFIB, carbonyl fluoride, and MFA. While EWG continues to track the changes in manufacturing practices for nonstick cookware, we highly recommend stainless steel and cast iron as great alternatives to nonstick cooking surface. Teflon is also used in clothing and carpeting that have stain repellent coatings, fast food packaging that repel grease and oil, cleaning products, and cosmetics.

Answer 4

Teflon, which is the commercial name of polytetrafluoroethylene, is a polymer of long carbon chains, each carbon atom being bonded to two other carbons and two fluorine atoms. Teflon is noted for its "anti-stick" properties, which result from the high electronegativity of the fluorine -- in other words, the fluorine's strength at holding the electrons in place prevents them to some degree from randomly clustering in areas to create temporary dipole-dipole moments (known as London dispersion forces), which can, in other materials, result in unwanted bondage.

Teflon is famously used to create non-stick cooking pans. It is also used to lubricate machinery to reduce friction (which is partially caused by London dispersion forces).

In addition to being slippery, Teflon is also a good insulator, with a far higher melting point than most plastics, so it is suitable for use in electric cables and circuit boards.

Teflon deforms under stress, conforming to the shape of whatever it is touching (a phenomenon known as creeping), which makes it an effective sealant.

Teflon's many marvelous and unique properties grant it a number of other uses.

Answer 5

It's a non-stick coating. It's designed to repel even burnt-on food - to make cleaning easier.

Answer 6

Teflon is used as a non stick coating on many objects. commercially it's used on frying pans and other hot cooking surfaces.
