A mixing agitator, for industrial use in mixing processes, that overcomes disadvantages associated with glass coated mixing agitators in the prior art. In particular, the mixing agitator includes a glass coated metal hub radially symmetrical about a central axis. The hub is at least partially embedded within a fluorinated polymer. The fluorinated polymer extends beyond the hub and forms agitator blades that may be reinforced. The hub has a centrally located receiving portion for receiving a drive shaft for rotating the agitator. The agitator is lighter weight than prior art glass coated steel agitators yet still has excellent chemical resistance and good temperature resistance. The agitator of the invention reduces likelihood of glass damage and permits agitator blade shapes not useable by glass coated agitators in the prior art. The invention also includes a mixing apparatus incorporating the hub and a method for mixing using the agitator.
