Military Silicone: MIL-DTL-25988, MIL-PRF-81322, MIL-DTL-83528, MIL-STD-417, WS14644
ElastaPro makes military silicones and fluorosilicones that meet MIL-DTL-25988, MIL-PRF-81322, MIL-DTL-83528, MIL-STD-417, WS14644, and other U.S. military specifications and standards. These specification grade silicone materials are available as solid silicone sheet or uncured silicone compound. Solid sheet materials arrives ready for die cutting and is betwen .010″ to .500″ thick with widths up to 60″. Uncured compound arrives ready for curing.
MIL-DTL-25988 Fluorosilicone
The MIL-DTL-25988 specification is structured to define the parameters and characteristics of fluorosilicone (FVMQ) materials, emphasizing their intended use in aerospace applications. It classifies the materials into various classes, considering factors like tensile strength, elongation, and durometer hardness. It also guarantees that the fluorosilicone meets stringent standards, providing reliability, durability, and performance across military conditions.
AMSR-25988 Fluorosilicone
AMSR-25988 is an SAE International specification that covers oil-and-fuel-resistant fluorosilicone elastomer rubber sheets, strips, molded parts, and extruded shapes for aeronautical and aerospace applications. It supersedes MIL-DTL-25988. ElastaPro provides AMSR-25988 fluorosilicone materials.
MILR-25988 Fluorosilicone
MILR-25988 (MIL-R-25988) is a U.S. military specification for fluorosilicone elastomer rubber designed for oil and fuel resistance, particularly in aerospace applications. It covers materials used for O-rings, molded parts, sheets, strips, and extruded shapes.
MIL-PRF-81322 Silicone
The MIL-PRF-81322 specification outlines general requirements for aircraft turbine engine lubricating oils. It does not specifically focus on silicone, but some lubricants that meet this specification may contain silicone-based additives. These compounds known for their thermal stability and oxidation resistance contribute to the lubricants ability to withstand high temperatures within turbine engines.
MIL-DTL-83528 Silicone
The MIL-DTL-83528 criterion outlines the specifications for electrically conductive silicone and fluorosilicone gaskets. These products are intended to offer protection against electromagnetic interference (EMI) and radio frequency interference (RFI). They are essential components in instances where shielding against such disruption is required to ensure electronic systems’ integrity and effective operation.
MIL-STD-417 Silicone
MIL-STD-417 is published by the U.S. Department of Defense and is the classification system and test standard for solid elastomeric materials (vulcanized rubber compounds).

WS14644 Silicone
WS14644 is a U.S. Department of Navy specification that establishes the requirements for vulcanized electrically conductive silicone rubber compounds. This specification applies to molded or extruded products or other shapes.
Conductive compounds that are covered by WS14644 are divided into types..
- Type I: Extremely high conductivity, silver filled
- Type II: High conductivity, nickel filled
- Type III: High conductivity, carbon black filled.
ElastaPro produces Type III materials.
WS14644 also contains three classes.
- Class 1: 45 +/- 7 Shore A hardness
- Class 2: 63 +/- Shore A hardness
- Class 3: 80 +/- Shore A hardness
