Antimony Oxide:
Antimony oxide is widely used in the aerospace industry as a flame retardant for plastics due to its excellent fire suppression properties. It works by releasing water vapor when exposed to high temperatures, effectively cooling the plastic and preventing further spread of flames. Antimony oxide-based flame retardants are commonly used in applications such as aircraft interiors, where fire safety is of utmost importance.
Aluminum Trihydrate:
Aluminum trihydrate is another popular flame retardant for aerospace plastics, known for its ability to release water molecules when heated, creating a cooling effect that inhibits combustion. This compound is commonly used in various aerospace applications, including cabin interiors and engine components, to enhance fire resistance and ensure the safety of passengers and crew members.
Organophosphates:
Organophosphates are a class of flame retardants that are favored in the aerospace industry for their high efficiency in reducing flammability and smoke emission. These compounds work by forming a protective char layer on the surface of plastics when exposed to fire, preventing the spread of flames. Organophosphate-based flame retardants are commonly used in aircraft wiring, insulation materials, and other critical components to meet stringent fire safety standards.
Boron Compounds:
Boron compounds are also widely utilized as flame retardants for aerospace plastics, offering excellent fire protection properties and low toxicity levels. These compounds work by releasing water vapor and carbon dioxide when heated, creating a barrier that limits the combustion of plastics. Boron compound-based flame retardants are commonly used in structural components, avionics, and other critical systems in aircraft to enhance fire resistance and ensure compliance with industry regulations.
