Taking into account the conclusions attained in the analysis about particle diameter, an analysis by separate<br />

of this variable was carried out for the samples with PVC 55% and fire retardant pigment V<strong>II</strong>I; for this study,<br />

the results connected with corrosion and blistering resistance were just considered (Table 6) since those<br />

obtained in both fire tests the particle diameters considered drove to similar results. Values included in Table<br />

6 show a strong influence of the particle diameter on the corrosion and blistering resistance; in the first case,<br />

the performance improved as the particle diameter decreased in the range studied (decreasing of permeability<br />

generated an increase in the barrier effect, Table 3) while in the second an opposite effect was determined<br />

(decreasing of permeability diminished the film capacity for the water vapor dissipation). For each particle<br />

diameter, average values for both tests are similar since themselves compensate; the last one fundaments the<br />

conclusion attained on this variable when values included in the Table 5 were analyzed.<br />
