Rubber

Used in seals, gaskets, and tires for landing gear.
Ethylene Propylene Diene Monomer (EPDM) A synthetic rubber valued in commercial aviation for its weather resistance and sealing capabilities
Fluoroelastomers (FKM) High resistance to jet fuels, hydraulic fluids, and chemicals, ideal for O-rings and seals in fuel systems.
Fluorosilicone Rubber (FVMQ) Resistant to fuel, oil, and extreme temperatures, commonly used in fuel system seals.
Hydrogenated Nitrile Butadiene Rubber (HNBR) Offers improved heat and oil resistance over NBR, used in high-performance sealing applications.
Natural Rubber Some aircraft tires contain natural rubber blended with synthetic rubbers to achieve optimal performance, grip, and wear resistance.
Neoprene (CR) Provides good resistance to ozone, weathering, and oil, used in various aircraft gaskets and hoses.
Nitrile Rubber (NBR, Buna-N) Excellent resistance to oil and fuel, often used in gaskets and hydraulic seals.
Polyurethane (PU) Used in aircraft wheels, insulation, and protective coatings due to its durability and abrasion resistance.
Silicone Rubber (VMQ) Used for seals, gaskets, and insulation due to its excellent temperature resistance (-55°C to 300°C).
