Mercer Gasket & Shim is a premier manufacturer of PTFE gaskets, which provide excellent chemical resistance and extremely low leak rates.
Able to withstand much more aggressive chemical environments than standard non-asbestos gasket materials, PTFE gasket materials are highly resistant to chemicals, solvents, caustics and acids, except alkali metals and fluorine gas. In addition, PTFE also has a very low surface energy and conforms to FDA regulations.
