Gasket Sheet Gambit AF-GL®

General properties and applications

Specially selected constituents and structure of AF-GL® gasket sheet ensure high tightness of a joint and resistance to a whole range of media, including steam, water, fuels, oils, solutions of salt as well as weak solutions of acids and bases.  Thanks to application of a unique composition of fibres and fillers, gaskets made of this material feature higher resistance to operation in steam.
