What can salt be used for in industry?

Answer

hi Kenny

Salt, NaCl, is an important raw material for industry.
The companies use salt to make chlorine, an important raw material for the production of the monomer vinyl chloride and from it the polymer polyvinyl chloride, better known as PVC. Many other substances are also produced with chlorine, it is a complete chain. You will find more information on the website of the chlorophiles (see link) and if you do some further searching on the internet.
And you are also familiar with the use of road salt, that too is usually and mainly NaCl.
If you want to know more, consult a library at a college or university in your area or search the internet, you will find information there, more than you can read.

Kind regards
