AMESSeal gasketing systems

The AMESSeal line of form-in-place gasketing systems is designed to improve sealing performance and reduce costs in proton exchange membrane (PEM), direct methanol (DMFC), and phosphoric acid (PAFC) fuel cells. The systems function by automatically dispensing and bonding a thin bead of low-durometer elastomers directly onto metal, graphite, or polymer substrates. Compared with traditional die-cut or molded gaskets, this system reduces possible sources of leakage by 50%. It does not require large upfront expenditures for tooling and molds, and becauseit is based on software-driven technology, it allows for low-cost prototyping and rapid scale-up to easily attainable production volumes. This system is also availablein a multi-layer composite version that combines silicone, which offers excellent compliance and sealing performance, with a fluoroelastomer, which has improved chemical and temperature resistance and durability.
