PGA rods are normally extruded at very low line speed and cooled down gradually through multiple cooling stages. This controlled cooling prevents cracking from thermal shock and allows the polymer to crystallize without accumulating excessive internal stress. However, because PGA exhibits significant volumetric shrinkage, it is still advisable to anneal the rod after extrusion to stabilize dimensions and relieve residual stress. For most applications, low‑temperature annealin

PGA is generally the superior dissolvable material for downhole tools compared with dissolvable metals (typically Mg‑based alloys) because it offers more predictable dissolution, higher initial mechanical stability, and cleaner wellbore cleanup, supported by recent engineering studies. PGA degrades by hydrolysis, which is governed mainly by temperature and water availability, giving operators a highly tunable dissolution window. PGA components can reach 50% weight loss in ~2.
