Definitions

  • the invention relates to filter means for high viscosity liquids involving a replaceable filtration unit or pack and to a process for the filtration of molten polymers employing such filter means.
  • molten polymers have high viscosity and are forced through the filter means under pressure, generally so as to be extruded into shaped articles such as filaments and films.
  • filtering means comprises inert granular material (16) immediately upstream of a supporting rimmed fine mesh screen (6) whose rim contacts the housing's internal lip (5), characterised in that the screen's rim is swaged into the housing, whereby there is a reduced chance of some of the liquid or granular material by-passing the screen.
