Engineers are faced with a multitude of material choices when asked to design a fluid handling system for corrosive environments. Because of the different properties necessary to produce rigid as opposed to flexible components, engineers may feel forced to choose materials with significantly different chemical structure to complete a system. Variables such as chemical resistance and temperature capability make each system that uses dissimilar materials a complicated design problem.

Fluoropolymer materials are commonly used in highly aggressive atmospheres in either solid form or as contact surfaces to protect metals from stress cracking. One problem with these materials, however, has been that throughout a given chemical process design, several different resins in combination may be needed to achieve an optimum cost performance design. Some new developments in the design of polyvinylidene fluoride resins can reduce or eliminate the number of resins used and the potential for incompatibility.
