WHILST examining the possibilities of applying rubber in low-temperature work, we were hampered by the lack of available data of its physical properties at low temperatures. We were quite aware of the difficulties to be expected in making accurate measurements in that temperature region, and this applies specially to the heat conductivity in which we were particularly interested. In order to obtain at least an estimate of the order of magnitude, we carried out some measurements of the heat conductivity of commercial rubber (tyre rubber, North British) at room temperature and the temperature of liquid air.
