摘要： A foamable polymer composition comprising a crosslinkable polymer, a crosslinking peroxide compound, and a chemical blowing agent comprising a functionalized particulate bicarbonate containing at least one additive. The additive may be selected from the group consisting of a fatty acid, a rosin acid, any derivative thereof, and salts thereof; or any combinations thereof, such as comprising abietic acid, dihydroabietic acid, neoabietic acid, a rosin acid ester, linoleic acid, or mixtures thereof. The particulate bicarbonate may be preferably functionalized by spray-coating, extrusion or co-grinding with at least one additive. The functionalized particulate bicarbonate may further comprise 0.1-5 wt % silica. A process for manufacturing a foamed crosslinked polymer, such as EVA and/or crosslinked polyolefins, and a foamed crosslinked polymer obtained by such process.
