This paper reports on the chemical surface changes of sepiolite, a natural magnesium silicate, caused by adsorption of 4‐amino methyl pyridine, and the application of this product as a reinforcing filler in epichlorhydrin rubbers. The amine group of the reagent used in the surface modification of the mineral reacts with elastomer upon vulcanization. This gives rise to stronger rubber‐filler bonds with the consequential improvement of the technological properties of the vulcanizates.
