Extrusion: Type- 30/25d (l/d = 25:1), Cooling- Air, Die- 0.2 mm, Pre-heating- 1 h @ 105ºC The filters used should be disks with holes of 1.5 to 5 mm. (depending on the screw and the die), and screen packs (the no. of meshes /cm2 will depend on the end product that is processed), so as to create a pressure built-up.
