POLYGLYCOLIC ACID RESIN COMPOSITION AND METHOD FOR PRODUCING THE SAME |
| 摘要 |
A polyglycolic acid resin (PGA) composition which can be used as a packaging material or a material for a drilling downhole tool (member), the composition containing from 30 to 90 mass % of a PGA and from 70 to 10 mass % of an inorganic filler, wherein the percentage of mass loss of the PGA after immersion in water for 3 hours at a temperature of 120° C. is at least 20% and preferably at least 25%, and the deflection temperature under load is 120° C. or higher; and a method for producing a PGA composition, the method including a step of melt-kneading using an extruder. |
