- Chemical and Fluid Resistance: These materials offer excellent resistance to aviation fuels, hydraulic fluids, oils, and other harsh chemicals commonly encountered in aerospace environments, ensuring long-term performance and safety.
- Environmental Stability: AMS elastomers are designed to resist degradation caused by ozone, UV radiation, and other environmental factors, making them ideal for use in the challenging conditions of aerospace operations.
- Low Outgassing: Many AMS elastomeric materials are engineered for low outgassing, which is crucial in space applications where contamination can affect sensitive equipment.
- Durability and Flexibility: AMS elastomers provide excellent mechanical properties, including flexibility, tensile strength, and compression set resistance, ensuring reliable sealing and vibration absorption in dynamic environments.
Common Applications of AMS Elastomeric Materials
AMS elastomeric materials are used in a variety of critical aerospace applications due to their high performance and reliability:
- Seals and Gaskets: AMS elastomers are commonly used in seals and gaskets for aircraft engines, hydraulic systems, and fuel systems, providing reliable sealing in extreme conditions.
- O-Rings: AMS-certified O-rings are widely used in aerospace components, including landing gear, engines, and flight control systems, where fluid resistance and temperature stability are essential.
- Vibration Dampening: These materials are used in vibration dampening systems to absorb shock and reduce vibrations in aircraft structures, improving safety and comfort.
- Fuel and Hydraulic System Components: AMS elastomers are used in hoses, seals, and diaphragms in fuel and hydraulic systems, ensuring compatibility with aviation fluids and providing long-lasting durability.
- Space Applications: In spacecraft and satellites, AMS elastomeric materials are used in seals and other components that require low outgassing and resistance to extreme space conditions, such as vacuum and radiation exposure.

EPDM (Ethylene Propylene)
AMS EPDM materials, O-rings, gaskets, & custom molded parts can operate over a wide temperature range, and are compatible with glycol fluids that cause problems for most typical elastomeric seals.
NBR (Nitrile, Buna-N)
AMS Nitrile O-rings, gaskets, & custom molded parts are very oil-resistant, have strong mechanical properties, are resistant to wear, and are relatively inexpensive. These properties make Nitrile the most commonly used general purpose O-ring, gasket, & custom molded part material.
HNBR (Hydrogenated Nitrile)
AMS Hydrogenated Nitrile O-rings, gaskets, & custom molded parts offer higher strength and reduced degradation at high temperatures compared to conventional Nitrile materials. These properties make HNBR materials popular in the oil and gas industry, as well as many applications in the chemical industry.
XNBR (Carboxylated Nitrile)
AMS XNBR O-rings, gaskets, & custom molded parts are similar to Nitrile, but the backbone has been chemically modified with a Carboxylic Acid group. The resulting elastomer is a Nitrile rubber with outstanding abrasion and chemical resistance, superior to that of traditional Nitrile.
Neoprene (CR)
Chloroprene was the first synthetic rubber, and was developed commercially under the name Neoprene®. AMS Chloroprene rubbers, O-rings, gaskets, & custom molded parts contain Chlorine in the polymer to reduce the reactivity to many oxidizing agents, as well as to oil and flame.
Polyurethane (PU, AU)
AMS Polyurethane O-rings, gaskets, & custom molded parts generally have two or three times greater tensile strength and wear resistance than Nitrile and comparable polymers. Polyurethane also provides excellent permeation resistance when compared to most rubbers.
Spring Energized Seal (SES)
The harshest environments require specialized solutions. Often times, a Canyon Components AMS Spring Energized Seal (SES) will be needed. SES are typically formatted in a multi-piece assembly consisting of a polymeric sealing component that is wrapped around a spring energizer.
