ABSTRACT:
A gasket is described which contains microspheres which expand inside the gasket sheet material after the gasket sheet is formed. Such gaskets are especially useful to provide a seal against fluid leaks at significantly lower pressures due to the presence of the microspheres. Some microspheres can expand during use.
