Patent for Rubber Research Institute of India
02 May 2013

Rubber Research Institute of India (RRII) got an Indian patent for the successful development of ‘Latex nanoclay composite’, a natural rubber nanocomposite. The Institute has acquired the skill for developing latex and dry rubber based materials which have fifty times air retention capacity than the virgin material. Rubber nanocomposites are also noted for their high resistance towards heat, solvents etc. Rubber composites filled with normal fillers like silica, carbon black requires a minimum of 30 – 40 per cent loading which finally will reduce the elastic behaviour of the material. Nanocomposites can solve these problems as the property enhancement can be carried out with lower additions; sometimes below one per cent. The new invention has great potential in tyre inner linings, meteorological balloons, protective gloves and condoms.
