Precision, safety, and efficiency are non-negotiable in the aerospace and defense industries, so choosing the right materials for key components is critical. Aircraft and defense systems are constantly exposed to aggressive fuels, mechanical stress, and wide temperature fluctuations, making material performance essential for operational success. Therefore, specialized jet fuel-resistant seals, poppets, gaskets and other custom molded aerospace rubber products support aircraft reliability and durability.
Here, we’ll take a closer look at the properties, applications, and benefits of aerospace rubber products for jet fuel systems.
Key Properties of Jet Fuel-Resistant Rubber
Jet fuel-resistant rubber materials are primarily synthetic elastomers, which are rubber-like polymers made by polymerizing petrochemical-derived monomers. Synthetic elastomers are widely known in the industry for their ability to maintain performance under dynamic conditions and mechanical stress. Common examples of aerospace elastomers include fluorosilicone, EPDM, Viton, fluoroelastomers (FKM), silicone, and nitrile.
Unique properties of jet fuel-resistant rubber include:
- Elasticity and strength. Aerospace elastomers maintain their elastic, durable properties even when exposed to challenging environments. Additives enhance strength, while plasticizers improve flexibility.
- Chemical and temperature resistance. These materials withstand repeated exposure to jet fuels, extreme temperatures, compression, and mechanical stress. Their durability means they perform reliably in these high-stakes environments.
- Customization. Synthetic rubber compounds can be tailored with curing agents to form cross-links between polymer chains, further boosting elasticity and longevity.
These properties make jet fuel-resistant rubbers indispensable for maintaining high performance and reliability in aviation.
Applications of Aerospace Rubber for Jet Fuel Systems
The jet fuel systems in aerospace and defense applications rely heavily on rubber components for tight sealing, protecting surrounding components, and ensuring efficiency:
- Sealing solutions. O-rings, poppets, gaskets, and seals made from materials like Viton are used to prevent leaks and degradation that can result from jet fuel exposure.
- Protecting critical components. Rubber materials like fluorosilicone are used in fuel tank access points, fuel line connections, engine seals, and pump seals to protect them and surrounding components from corrosive materials.
- Fuel system efficiency. Choosing the right rubber material minimizes the risk of seal failure, which is crucial for safety and operational efficiency.
Safety and Durability Benefits
The benefits of jet fuel-resistant rubber extend beyond functionality. These materials contribute significantly to safety and durability in key aerospace applications, including the following:
- Shock and vibration absorption. The rubber’s elasticity allows it to adapt to various shapes and sizes, making it ideal for absorbing shock and vibrations in aircraft systems.
- Extreme weather resistance. EPDM and silicone are particularly capable of withstanding extreme temperatures and environmental conditions over long periods of time.
