Abstract

The invention relates to molded getter bodies for use in encapsulated electrical components. The getter bodies are formable into compressed body shapes in a simplified manner from a mixture of (A) a getter material consisting of activated carbon, zeolite, zirconium and mixtures thereof, (B) polyamide, and (C) polyethylene wax. The molded getter bodies of the invention have improved accuracy as to size, increased getter capacity, and uniform getter activity relative to the prior art.
