Plastics vapour corrosion effects

Table 18.18 summarises the reported vapour corrosion effects of a variety of plastics references to the source of the information is given at appropriate places. 

Table 18.18 Summary of vapour corrosion effects of plastics...

Glass reinforced plastics normally have good corrosion resistance against a variety of chemicals and aggessive environments. This is mainly associated with the inertness of the resin, which can be formulated to confer chemical resistance. The main effects of exposure to fluids or vapour is swelling and debonding as a result of absorption by the matrix. Under stress the resistance of resins and fibres to an environment may be reduced through the interaction of the stress with the internal forces. Indeed stress can accelerate the permeation of fluids into the polymer structure in a similar way to temperature.
