Abstract:
A solidification- and extrusion-molded article of polyglycolic acid, which is formed of a resin material containing polyglycolic acid, the polyglycolic acid having a melt viscosity of 200 to 2,000 Pa·s, and has a thickness or diameter of greater than 100 mm but not greater than 500 mm. A downhole tool or a component thereof and a ball sealer for petroleum excavation are formed by cutting the solidification- and extrusion-molded article. A method for manufacturing the solidification- and extrusion-molded article of polyglycolic acid and a method for manufacturing a ball sealer for petroleum excavation.

Claim (Index 10):
A method for manufacturing a solidification- and extrusion-molded article of polyglycolic acid, the method comprising steps 1 to 4 below:\n a) step 1 of supplying a resin material containing polyglycolic acid, the polyglycolic acid having a melt viscosity of 200 to 2,000 Pa\u00b7s upon being measured at a temperature of 270\u00b0 C. under a shearing speed of 120 sec \u22121 , into an extruder, and melt-kneading the resin material at a cylinder temperature of the extruder of 240 to 285\u00b0 C.; b) step 2 of extruding the resin material, melted by the melt-kneading, from an extrusion die at a tip of the extruder into a flow path of a forming die comprising cooling means and the flow path that communicates with a path of melted resin of the extrusion die and that has a cross-sectional shape of an extrusion molded article; c) step 3 of solidifying the melted and extruded matter formed from the resin material by cooling in the flow path of the forming die, and then extruding the solidified and extruded matter from the tip of the forming die to outside; and d) step 4 of pressurizing the solidified and extruded matter, and drawing the same while applying back pressure thereto in a direction of the forming die to suppress expansion of the solidified and extruded matter in a thickness direction or radial direction to obtain a solidification- and extrusion-molded article of polyglycolic acid having a thickness or diameter of greater than 100 mm but not greater than 500 mm.
