The various embodiments of the present invention disclose an peroxide-vulcanised TPVs based on Hevea Brasiliensis natural rubber, polypropylene and solid sulfonic acid doped polyaniline [PAni.DBSA] with useful electrical conductivities (up to about 2.1±0.2 S/cm] can be produced by using an internal mixer. The peroxide-vulcanised TPVs exhibit useful physical properties and also possess a reasonable good electromagnetic interferences shielding effectiveness. These peroxide-vulcanised TPVs could be recycled up to 4 times without significant loss of their EMI SE, electrical and physical properties. As a result, they have good potential to be used for manufacturing any EMI shielding products, such as EMI shielding seals and gaskets.
