A trend towards miniaturization of equipment and accompanying higher operating temperatures exists in many phases of the electrical industry today. This trend, especially when coupled with the many military applications requiring a high degree of thermal stability, has indicated a need for new high-temperature insulation components. Such a need has been further crystallized by the inadequacies of many presently used high-temperature insulations with respect to fabrication properties, solvent and oil resistance, and system compatibility. This situation has sparked considerable research activity aimed at the development of new heat-resistant materials with improved auxiliary properties.
