ABSTRACT:
A flowable, pressure-compensating material, confined in an envelope, comprises a flowable, continuous-phase of oil having dispersed therein discrete hollow microbeads and a colloidal silica. The pressure-compensating material, which is flowable in response to continuously applied pressure, but is essentially non-flowable in the absence of pressure, is relatively insensitive to temperature variations.
