IMPROVED ELECTROLYTIC CAPACITOR COVER, METHOD AND MATERIALS FOR THE MANUFACTURE THEREOF

摘要

Improved covers for electrolytic capacitors, offering both durability and low extractibility of halides by high temperature electrolytes, can be produced from molding compositions comprising thermoset polymers having low halide extractibility, preferably based on materials such as phenolic resins, and nonporous fillers, the compositions preferably being essentially free of porous fillers.
