<p>A sealing member for an electrochemical cell is formed of a high impact modified styrenic polymer blend which may include a styrenic polymer and an impact modifying agent which increases the toughness of the styrenic polymer. The styrenic polymer based sealing member has several advantages over conventional cell seals and sealing gaskets, including lower cost, better processability and improved chemical resistance to alkaline medium. Also provided are galvanic cells including the seal member, in particular miniature alkaline air cells including the seal member as a gasket.</p> |
