Critical Applications in Aeronautics and Space

Technical silicones from ProSilicones64 are used in sealing, insulation, and thermal protection systems where safety and weight are critical factors:

Fire-retardant seals and profiles → cabins, fairings, fuselages, and service compartments
Fluorosilicone cords → sealing of tanks, valves, and hydraulic circuits
Multi-layer profiles → climate control, pressurization, and ventilation systems
Molded parts → connectors, valves, stoppers, and technical diaphragms
Thermal insulation → electrical equipment, sensors, and aeronautical wiring
Anti-vibration mounts → dynamic absorption in lightweight structures
Door and hatch sealing → FAR 25.853 fire-retardant materials
Aerospace components → precision seals for satellites and launchers
Additional solutions
