Natural rubber latex nano composites were prepared by conventional compounding technique using layered silicates(hydrated aluminium silicate) and were used in the production of natural latex condoms. They are readily dispersed in water (latex) and are easily incorpoarated as an aqueous dispersion without risking the destabilization of the latex.An appropriate level of layered silicate having particle size～100nm with a layer thickness of 40-60nm is used as fine dispersions during compounding.The addition of(5% aqueous) layered silicate reduced the protein content of Natural Rubber Latex to below detection levels. Biological studies proved that the condoms free from any toxicity. Mechanical properties like tensile & elongation show improvement while air permeability and moisture absorption reduced with the incorporation of nanosilicates. The transparency of resulting latex film was improved. The stiffness of the product is improved by the addition of nanosilicates and attributed to reduction on latex consumption for the product.
