US Patent 11840614 Methods of manufacturing high temperature conformable polymeric screens

A method of manufacturing a fluid control device includes extruding a polymer melt into a chamber defined by an outer surface of a support structure and a disintegrable metallic tubular member disposed at the support structure, the polymer melt comprising a high heat polymer and a foaming agent, the high heat polymer having a heat deflection temperature of about 100° C. to about 300° C. measured at 1.82 MPa in accordance with ASTM D648-18; sealing the chamber; and foaming the high heat polymer to produce a porous filtration medium in a compacted shape.
