EVALUATION OF BUNA-N (NBR) GASKETS IN PROTOTYPE APPLICATIONS UNDER GAMMA FLUX

Abstract

Qualitative and quantitative sealability tests were evaluated to test the theoretical prediction of he ability of certain acrylonitrilebutadien rubber s ocks Reasonable agreement betw n s alability coefficients was obtai ed from the seal tester and relative replaceme t imes ov r dose range from 2 x 10 to the 9th power to 2 x 10 to the 10th power ergs/g C (one roentgen = 87.7 ergs). Evaluation criteria for these compositions were established by application of the Bopp-Sisman relations ip to obs rv d changes in the elastic modulus previously reported. The effect of ferrocen as a pot ntial anti-rad wa inv stig ted and found to improve the radiation resistance of these stocks. The apparatus described for determining sealability of gasket materials consist of a method of applying a load on the gasket, equipment for pressurizing one side of the gasket seal and a method for measuring gas leakage.
