An aqueous dispersion of granular PTFE particles and a melt-flowable fluorinated polymer powder particles is sprayed or cast to form a sheet. The sheet is then dried and the particles fused together to form an open network of fused interconnected particles that define a tortuous network of voids through the sheet. It has been found that when melt-flowable fluorinated polymers are present, the resulting fused sheets are stronger than when the fluorinated polymer is not present.

Une dispersion aqueuse de particules de PTFE granulaires et de particules pulvérulentes d'un polymère fluoruré fluidifiable par fusion est pulvérisée ou coulée pour former une feuille. Cette feuille est ensuite séchée et les particules sont réunies par fusion pour former un réseau ouvert de particules fondues interconnectées définissant un réseau tortueux de vides dans la feuille. Il a été démontré qu'en présence de polymères fluorurés pouvant être fluidifiables par fusion les feuilles fondues résultantes sont plus résistantes qu'en leur absence.
