The nano CaCO3 was added, from mass fraction (w) 1 % to 5 %, in the styrene butadiene styrene elastomer (SBS). Elastomer nanocomposites were compounded on a two-roll mill and molded in a compression-molding machine. The mechanical properties such as the tensile strength, the elongation at fracture, the modulus at 300 % elongation, the hardness, the specific gravity, the swelling index, and the flame retardancy were studied. The results were compared with a commercial CaCO3 (mum) filled SBS. There was an improvement in the properties of the elastomer nanocomposites because of the uniform dispersion of the nano CaCO3 particles in the matrix that intercalates the elastomer chains. Hence, the degree of cross-linking increases multifold in comparison with the commercial CaCO3"},{"@xml:lang":"sl","#text":"Uporabljeni so bili delci CaCO3 različne velikosti, potrjeni z metodo rentgenske difrakcije.

Preizkušene so bile mehanske lastnosti, kot so natezna trdnost, raztezek pri porušitvi, modul pri 300-odstotnem raztezku, trdota, specifična gostota, indeks nabrekanja, zadrževanje širjenja plamena. Rezultati so bili primerjani s komercialnim SBS, polnjenim z mikrodelci CaCO3. Ugotovljeno je bilo izboljšanje lastnosti elastomernega kompozita zaradi enakomerne razpršenosti nanodelcev CaCO3 v osnovi, kar omogoča vrinjenje verig elastomera.
