ABSTRACT:
A Polyphenylene Sulfide (PPS) seal for a cell for Alkaline cells, Mercury cells, or NiCad cells. The seal is not susceptible to leakage due to thermal excursions, thermal shocks, or long term storage. The all-polymer seal is of a predetermined geometrical configuration and provides a seal of a material composition for sealability of a cell between the negative or positive terminal cap and the cell can. The PPS seal can also include glass fiber and/or a composition from the olefin family.
