In an effort to address the Chemical Processing Industry (CPI) market demands for
effective corrosion protection and friendlier processing, new grades of lower melting point
perfluoro-alkoxy resin, also known as MFA, have been developed recently.
MFA belongs to the generic class of PFA fluoropolymers as specified in the ASTM
D3307. It has a 30-40°C lower melting point when compared to type I-III, traditional PFA resins
with comparable mechanical properties, chemical resistance, and permeability.
PFA resins are commonly used in corrosion protection applications such as the coatings
and linings of process vessels, storage tanks, pipes, and valves and fittings. They can
successfully replace metals in several free-standing applications. The excellent
performance/price ratio of MFA fluoropolymers makes them very attractive in CPI applications.
