Abstract: A curable elastomer composition includes a crosslinkable polymer, and a filler selected from surface-reacted calcium carbonate, precipitated hydromagnesite, or a mixture thereof, wherein the surface-reacted calcium carbonate is a reaction product of natural ground calcium carbonate or precipitated calcium carbonate with carbon dioxide and one or more H3O+ ion donors, wherein the carbon dioxide is formed in situ by the H3O+ ion donors treatment and/or is supplied from an external source. Furthermore, the disclosure relates to a cured elastomer product formed from said composition, an article including the cured elastomer product, a method of producing a cured elastomer product, and use of the filler for reinforcing a cured elastomer product.
