Nylon is made from two chemical compounds: Hexamethylenediamine consists of carbon, nitrogen and hydrogen. Adipic acid contains carbon, hydrogen and oxygen. Each of these substances contains six carbon atoms and the Nylon-6, 6. Manufacturers combine the two compounds to form a substance called nylon salt.ylon is made from two chemical compounds: Hexamethylenediamine consists of carbon, nitrogen and hydrogen.
