Factors influencing the sealing characteristics of gaskets made from asbestos-reinforced rubbers include mechanical properties, thermal properties and moisture absorption characteristics. Existing knowledge of the temperature dependence of the mechanical behaviour has been augmented by investigations of the specific heat capacity, thermal expansion and thermal conductivity at temperatures up to 250° C, as well as moisture absorption characteristics at ambient temperature of as-prepared and thermally cycled material. The measurements have provided an insight into thermally induced structural changes within the matrix, which are relevant to component operation. |
