Abstract: A porous filler for reducing the gas permeability of an elastomer composition, a process for producing the elastomer composition comprising the porous filler, and the elastomer composition itself. The porous filler is selected from surface-reacted calcium carbonate, precipitated hydromagnesite and mixtures thereof. The addition of the porous filler to the elastomer composition allows for reducing the gas permeability of the elastomer composition while retaining or improving the mechanical properties of the elastomer composition.
