Fluoroplastics show the best chemical resistance among the plastics. Fluoroplastics are
inert to almost all kinds of chemicals in the temperature range of -60 deg C to 260 deg. C.
Fluoroplastics show excellent non-stick properties and low friction properties, giving these
materials widespread use in the chemical and oil and gas industries. The physical and
chemical properties of the different kinds of fluoropolymers will be discussed. The applications
in this paper will focus on the coating process vs. the lining process with pros and cons. The
coating process will be presented in detail. Examples will be presented on the different types of
applications. Finally, six cases will be presented. One of the cases will be desulfurization of
flue gas at high temperatures.
