Fluoropolymers are a class of olefinic, thermoplastic polymers where some or all of the hydrogen has been replaced by fluorine. The result is either a fully fluorinated polymer such as PTFE and PFA, or a partially fluorinated polymer, such as ECTFE. This type of polymers has very high resistance to chemical corrosion in the most acidic and alkaline environments, for this reason and also because of the high temperature resistance, they are widely used in the chemical industries.
These coatings are applicable on the inner surfaces of chemical industry equipment such as tanks, columns, pipes, fittings and valves. Of course, coating method; due to the nature and condition of any of fluoropolymers and also corrosive environments and equipment design, Should be determined by our experts. 
Fluoropolymer types which are used in the Shimi Azar Jaam as a coating on the internal surfaces of equipment are as follows:
