Question

Which polymer is used for making non-stick utensils?

Answer 1

As we know that polymers are very large molecules or macromolecules which are made up of repeating units which are called monomers. And normally non-stick utensils are generally made up of a thermoplastic polymer which is white solid at room temperature and maintains high strength.

Complete answer: As we know that non-stick utensils are generally made up of poly tetra fluoro ethylene (PTEE) which is commonly called Teflon having monomer tetrafluoroethylene and the repeating unit is shown as $- C{F_2} - C{F_2} -$. This compound is non-reactive because of the strong carbon-fluorine bonds in it, therefore it is used as a non-stick coating for utensils like pans and other cookwares.
Teflon is a thermoplastic polymer and is present as a white solid at room temperature. It possesses a high strength and toughness at low temperature and are flexible at high temperatures.
These chemicals are affected with highly reactive metals like alkali metals. And due to its hydrophobicity and high heat resistance, it is used in making non-stick utensils. It is non-toxic and stable at low temperatures but when the temperature begins to rise, it starts deteriorating and decomposes at high temperatures.
Therefore, from the above explanation we can say that the correct answer is Teflon.

Note: Along with manufacturing of non-stick utensils, poly tetra fluoro ethylene is used for the insulation of wiring in computer applications like hookup wires, coaxial cables as well as in aerospace. It is also used in making gears, slide plates, plain bearings, gaskets etc. it is also used as a lubricant in musical instruments.
