Abstract
The present invention relates to a plastic blend of polymers, capable of being injected and extruded, the process for producing it and its applications. This blend is produced by extrusion of a matrix of heat-stable material consisting of a polysulfone resin or polyphenylene sulfide and of a filler of a fluorocarbon polymer resin, the extrusion producing a network of interconnected and inter-penetrated fibers of filler within the matrix. This blend can be employed in an aggressive environment and at a high temperature, particularly for the manufacture of components of electrochemical reactors such as electrolysis cells.
