Ks. Mohanadas et B. Kuriakose, STUDIES ON THE EFFECT OF FILLERS ON AIR PERMEABILITY OF NATURAL-RUBBER VULCANIZATES, Kautschuk und Gummi, Kunststoffe, 50(7-8), 1997, pp. 544-548
Compounds of natural rubber containing different fillers were evaluate
d for their air permeability, The results indicated that incorporation
of filler generally reduce the permeability, but certain fillers such
as mica, graphite and clay produced substantial reduction which was a
ttributed to the particular morphology of these fillers as evidenced f
rom photomicrographs. Physical properties were mostly lowered, with ex
ception of carbon black.
