1. A foamable polymer composition comprising:
a crosslinkable polymer, selected from the group consisting of polyolefins (PO), polyolefin elastomers (POE), polyolefin block co-polymers (OBC), ethylene vinyl acetate copolymers (EVA), EVA/PO copolymers, EVA/OBC copolymers, and combinations thereof,
a crosslinking peroxide agent and
a chemical blowing agent comprising a functionalized particulate bicarbonate, wherein said functionalized particulate bicarbonate comprises abietic acid, dihydroabietic acid, neoabietic acid, any ester of abietic acid, any ester of dihydroabietic acid, any ester of neoabietic acid, any salt of abietic acid, any salt of dihydroabietic acid, any salt of neoabietic acid, or any combination thereof.
