What is the formula for tetrafluoroethylene?


What is the monomer of tetrafluoroethylene?

Teflon is a polymer, which is made by joining together lots of smaller molecules called monomers. In this case, the monomer is tetrafluoroethene (TFE), and when polymerised it becomes poly-TFE, or PTFE as it’s sometimes called.

What type of polymerization is tetrafluoroethylene?

Polytetrafluoroethylene, or PTFE, is made of a carbon backbone chain, and each carbon has two fluorine atoms attached to it. Polytetrafluoroethylene is made from the monomer tetrafluoroethylene by free radical vinyl polymerization.

What is the functionality of tetrafluoroethylene?

The main use of tetrafluoroethylene is in the manufacture of polytetrafluoroethylene that is used as nonstick coatings on cookware, membranes for clothing that are both waterproof and breathable, electrical-wire casing, fire- and chemical-resistant tubing, and plumbing thread seal tape.

What is the difference between TFE and PTFE?

Tetrafluoroetheylene, also referred to as TFE, is a synthetic fluoropolymer more commonly known as Teflon®. Teflon® is the broader material while FEP, PTFE, and ETFE are subsets of Teflon®. TFE can withstand very high and low temperatures, is extremely durable and exhibits excellent electrical properties.

What is the formula of empirical formula?

The empirical formula of a compound is the simplest whole number ratio of atoms of each element in the compound. For example, the molecular formula of glucose is C 6H 12O 6 but the empirical formula is CH 2O.

Why is polytetrafluoroethylene unreactive?

PTFE has a high molecular weight and is generally an unreactive substance due to the highly stable nature of the fluorine and carbon bonds in its structure. Furthermore, the high electronegativity of the fluorine atoms gives the plastic an extremely water repellent surface and outstanding non-stick properties (Fig.

Why is Tetrafluoroethene inert?

However, instead of reactive C-H bonds which occur in most polymers, Teflon has all its hydrogens replaced by fluorines. These strong C-F bonds are extremely resistant to attack by any other reagents, making Teflon very inert. This means that no other molecules will react with or stick to Teflon.

What are the disadvantages of PTFE?

There are some disadvantages to PTFE which give the product some limitations. For example, when overheated, it can release mildly toxic fumes. In addition, its abrasion-resistance is not as good as a number of other coatings and so abrasion resistance isn’t its primary advantage.

Is PTFE and Teflon tape the same?

That’s right, Teflon is PTFE but by another name. Teflon is the trademarked brand name for PTFE owned by Chemours, and just as we call our vacuums Hoovers and sticky tape Sellotape, so we’ve come to know PTFE by the name it was given.

What is difference between empirical formula and molecular formula?

The empirical formula of a compound gives the simplest ratio of the number of different atoms present, whereas the molecular formula gives the actual number of each different atom present in a molecule. …

What is empirical formula with example?

Empirical Formula Examples Glucose has a molecular formula of C6H12O6. It contains 2 moles of hydrogen for every mole of carbon and oxygen. The empirical formula for glucose is CH2O. The molecular formula of ribose is C5H10O5, which can be reduced to the empirical formula CH2O.
