does not seem to exert a meaningful influence on results.

Taking into account the conclusions attained in the analysis about particle diameter, an analysis by separate
of this variable was carried out for the samples with PVC 55% and fire retardant pigment VIII; for this study,
the results connected with corrosion and blistering resistance were just considered (Table 6) since those
obtained in both fire tests the particle diameters considered drove to similar results. Values included in Table
6 show a strong influence of the particle diameter on the corrosion and blistering resistance; in the first case,
the performance improved as the particle diameter decreased in the range studied (decreasing of permeability
generated an increase in the barrier effect, Table 3) while in the second an opposite effect was determined
(decreasing of permeability diminished the film capacity for the water vapor dissipation). For each particle
diameter, average values for both tests are similar since themselves compensate; the last one fundaments the
conclusion attained on this variable when values included in the Table 5 were analyzed.
