RJ-4 (MIL-F-82522) Chemical compatibility with O-rings, rubbers, & plastics

RJ-4 (MIL-F-82522) is a high-energy rocket propellant used in military and aerospace applications. It is a kerosene-based fuel designed to provide superior performance in rocket engines, delivering high thrust and efficiency. RJ-4 is formulated to meet rigorous military specifications, ensuring reliable performance under extreme conditions. It offers excellent thermal stability, low freezing point, and high energy density, making it suitable for advanced rocket propulsion systems. RJ-4 is also designed to minimize deposits and corrosion, enhancing engine longevity and performance. Its consistent quality and performance characteristics make it a preferred choice for military and aerospace applications. However, RJ-4 is highly flammable and requires careful handling and storage to prevent accidents and ensure safety. Proper safety measures, including the use of appropriate protective equipment and adherence to handling protocols, are essential when working with RJ-4 rocket propellant.
