Polyimide ML Insulation is key to performance and longevity in space

The uses for Polyimide ML insulation (thermal class 240°C) are high-temperature continuous duty coils, hermetically sealed relays, and fractional and integral HP motors. This insulation is primarily used in the aerospace industry due to its minimal outgassing property.

Aerospace Wire applications – Because of its thermal insulation and radiation resistance properties, Polyimide (ML) is used to wind coils on satellites, spacecraft and launch vehicles. Other uses include avionics, navigation, flight controls, wing movement, and collision avoidance.

Electronic applications – Polyimide (ML) film is ideal for high heat environments, such as wheel speed sensors, brake control systems and for the majority of applications in all Aerospace market segments.

Polyimide Varnish for Heat-Resistant Insulation Coating:
This resin not only has excellent heat stability, but also great mechanical and electrical characteristics and reliability, thus achieving a long history of use and popularity. These applications continuously are expanding to include use in insulated covers for heat-resistant wires, as well as parts used in airplane production and industrial equipment.
