| 摘要 |
The present invention relates to an electrolytic cell having a flexible, heat-resistant elastomeric blanket separating the inside of the cell compartment and the base member. The blanket is fabricated of a thermoplastic elastomeric material. The material is comprised of a blend of thermoplastic polyolefin resin, such as polypropylene or polyethylene, with a polyolefin rubber, preferably a polyolefin rubber such as ethylene-propylene copolymer, i.e., EPM or EPDM. Other rubbers, such as butyl, neoprene or natural rubber may be utilized; however, polyolefin rubbers facilitate particularly useful blends. The polyolefin rubber component may be lightly cross-linked. It is preferred that the polyolefin rubber component be substantially fully cross linked and that the crystalline polyolefin resin be the only component in continuous phase.
