摘要:
An impermeable elastic membrane for hydropneumatic accumulators is made from an impermeable film of completely hydrolyzed polyvinyl alcohol, with a high molecular weight, and plasticized, with protective layers on both sides of polyamide, ethylene vinyl alcohol, or ethylene vinyl acetate. The membrane may be used in the hydropneumatic suspension of an automobile. The film can be obtained by extrusion, by injection molding, or by pressure molding.
