AMS Silicone

ElastaPro Silicone Sheeting offers AMS silicone in solid sheets and uncured silicone compounds. These elastomers meet Aerospace Material Specifications (AMS) from SAE International and are made to strict quality control standards. AMS silicone materials engineered for precision, durability, and reliability and used in aerospace, military, and industrial applications.

AMS Silicone Solid Sheets

AMS solid silicone sheeting is manufactured to meet strict aerospace standards and arrives ready for die-cutting. It is available in thicknesses ranging from .010” to .500” and in widths of up to 60”. This material is designed for applications requiring high heat resistance, flexibility, and long-term durability.

Manufacturers and engineers rely on AMS silicone sheets for their ability to maintain performance under extreme temperatures. The material resists aging, weathering, and compression sets, making it an excellent choice for seals, gaskets, and insulation components used in high-stress environments.

AMS Silicone Uncured Compound

For applications requiring custom curing, we can provide AMS-compliant uncured silicone compounds. These compounds allow for molding, extrusion, or calendering to create precision components that meet specific performance requirements. Delivered in an uncured state, this silicone is engineered for processing flexibility, ensuring it meets the exact needs of a given application.

AMS uncured silicone is chosen for projects that demand strict compliance with aerospace and industrial material standards. Its formulation is designed to maintain integrity under demanding conditions, providing both thermal and chemical resistance.

Industry Applications

AMS-compliant silicone is used in aerospace, industrial, military, and electrical applications where durability and heat resistance are essential.

In aerospace, it is commonly found in door and window seals to prevent air leakage and protect against moisture and UV exposure. Firewall gaskets use it to shield components from extreme heat, while landing gear seals rely on its ability to withstand pressure changes and hydraulic fluids. It is also used in engine and exhaust system seals, where resistance to high temperatures and chemical exposure is critical.

For industrial equipment, AMS silicone is used in ovens and furnaces as a sealing material that can withstand prolonged high temperatures. In chemical processing, it serves as a protective barrier against aggressive chemicals. HVAC systems use it in ductwork and insulation to improve efficiency, while pumps and valves depend on it to maintain reliable sealing under demanding conditions.

In military and defense applications, AMS silicone is used in vehicle and aircraft seals to provide protection against harsh environmental conditions, including extreme temperatures, pressure changes, and exposure to fuels and lubricants. It is also applied in weapon systems and communications equipment, where consistent performance is necessary for reliability in the field.

Electrical insulation is another key use, as AMS silicone protects sensitive electronics from temperature fluctuations, moisture, and environmental exposure. It is found in wire and cable coatings, circuit board protection, and high-voltage insulation, ensuring stable operation in both commercial and defense-related applications.

What are AMS Standards?

AMS, or Aerospace Material Specifications, are a set of standards developed by SAE International specifically for materials used in aerospace and defense applications. These standards ensure that materials meet precise criteria for composition, mechanical properties, and performance under various environmental conditions. AMS specifications cover a wide range of materials, including metals, alloys, composites, and plastics.
