A STUDY OF THE COMPRESSION OF POLYTETRAFLOURO ETHYLENE (TEFLON) AT ULTRAHIGH PRESSURES,
Abstract
This study of Teflon was done in order to deter mine the possible side effects of the compressi bility of Teflon in relationship to its inciden tal use in the Uni-Ram. Teflon is used in the Uni-Ram set-up as anti-friction sheeting between each anvil base and the tapered cone surface; it is also used as spacer discs between the anvil side faces in centering the sample and anvils. Conclusions of the data obtained in these com pressive studies of Teflon must be somewhat lim ited due to lack of absolute pressure values. It is apparent that the compressibility factors of Teflon do contribute to the overall h' (closing movement of the top anvil in respect to the bot tom support surface of the Uni-Ram, expressed in thousandths of an inch) values obtained with the Uni-Ram set-up. There is an indication that a possible calibration point will be valid in the range of zero to ten tons Ram Force, or the equiv alent of about five kilobars. (Author)
