COMPATIBILITY OF SEVERAL PLASTICS AND ELASTOMERS WITH SODIUM, POTASSIUM, AND RUBIDIUM

Abstract

Fourteen representative plastic and elastomer samples were immersed in Na K, or Rb from 3 to 10 days at 250 or 350 F to determine their compatibility with these alkali metals. Changes in weight, hardness, tensile strength, percent elongation, and flexibility were measured, and changes in appearance were noted. A selection was made of materials that were expected to yield minimum contamination to the alkali metals and that showed no appreciable degradation of physical properties under the various conditions of time and temperature. First and second selections were as follows: First, Na at 250 degrees, Kel-F 3700; Na at 350 degrees, Neoprene; K at 250 degrees, Buna-S; Rb at 245 degrees, Neoprene; Buna-N was the second selection for the 4 categories.
