Aerospace and Defence

Mica plays a crucial role in the aerospace and defence industries, where it is used in a wide range of high-performance and safety-critical applications. It is an essential component in air-, ground-, and sea-launched missile systems, radar systems, and various other defence-related electronic devices. Thin layers of mica remain stable even at the micrometer scale, allowing partial transparency to radiation while maintaining resistance to most gases and extreme environmental conditions. Its exceptional thermal stability and fire-resistant properties make it indispensable in high-temperature power and signal cables used in defence plants, surveillance networks, and alarm systems. Mica-taped cables are particularly valued for their reliability in critical operations such as firefighting, heat shielding, and flame retardation. Owing to its outstanding heat endurance, mica continues to be a preferred material for insulation and protection in modern aerospace and defence technologies.
