Filling a gap in the rubber industry

Sri Lanka recorded rubber products exports worth US$ 855M in 2017. The annual gross turnover of the Sri Lankan rubber industry is estimated at approximately US$ 1 billion. Our world-acclaimed natural rubber (NR) products include solid tires and surgical gloves.

The unique mechanical properties of NR can be modified by vulcanizing and addition of fillers as per the requirement for a specific application. Carbon black is a widely used reinforcing filler. The appearance of black color in the product, and environmental pollution are its main limitations. Hence, Jayaraj investigated  inexpensive and environment-friendly alternatives. The introduction of such a filler would bring significant economic advantages to the dry rubber industry in Sri Lanka.

He identified clay (Montmorillonite) as a suitable reinforcing filler, and carried out experimental investigations on preparation of the NR-clay nanocomposite and the resulting mechanical properties.  Jayaraj found that this material is an excellent reinforcing filler at low loadings.
