Estimation Procedures of Inhibited Plastics Efficiency

Early inhibited packing films developed in the USSR in the 1970s were polymer films with glued volatile Cl on one side [76]. Further elaboration of this idea has lead to melt-blown materials whose fibers carry particles of Cl (Fig. 1.17). 

This class of inhibited plastics includes multilayered films containing particles of a powder inhibitor between its polymer layers. 

Successes in plastics technology have spurred the progress of composites with a microporous polymer matrix having a layer of solid phase inhibitors deposited by sublimation on pore walls. These materials are mainly designed for protection of friction joints against corrosion under both static and dynamic conditions. 

The aforementioned plastics will be described in this book. Unusual testing methods are needed to characterize the structure and behavior of these multifunctional active materials used in numerous domains. Most of these materials conform to the concept of smart materials and have a great future. 

The efficiency of the level of protection from corrosion damage of inhibited plastics is characterized by their protective ability. Estimation procedures are specified by certain standards of the International Organization for Standardization (ISO) as well as by the corresponding standardization organs of a number of countries and industrial branches.
