LMA Silicone: LMA-ME025 and LMA-STM
ElastaPro makes LMA silicone that meets several Lockheed Martin specifications.
LMA silicone from ElastaPro meets Lockheed Martin Aeronautics (LMA) requirements. Choose these specification grade silicone materials as solid silicone sheet or uncured silicone compound in the durometers, sizes, and colors that you need. ElastaPro makes aerospace silicones that meet LMA-ME025 and LMA-STM requirements. We are AS9100D and ISO 9001:2015 certified.
LMA-ME025 Silicone
LMA-ME025 is a material specification used by Lockheed Martin Aeronautics (LMA) for certain silicone materials. The specification details the specific properties, quality control, and testing methods that the material must meet to be approved for use in aeronautical applications.
The detailed requirements for LMA-ME025 are proprietary to Lockheed Martin. A manufacturer seeking approval to produce a material to this specification must follow the procedures for qualified suppliers, which includes certification processes.
Key Material Characteristics
- Material type: Solid silicone elastomer or uncured silicone compound
- Durometer range: Commonly 30–70 Shore A depending on application
- Thermal stability: Maintains mechanical properties across wide temperature ranges typical of aerospace environments
- Environmental resistance:
- UV and ozone resistant
- Low compression set
- Stable under humidity and weathering
- Manufacturing formats:
- Sheet stock (various thicknesses)
- Uncured compound for molding or extrusion
- Quality standards: Often produced under AS9100D and ISO 9001:2015 quality systems for aerospace compliance
Typical Aerospace Applications
- Access‑panel gaskets
- Avionics and electronics enclosure seals
- Thermal and environmental barrier pads
- Vibration‑damping interfaces
- General-purpose aerospace gasketing where silicone is specified by LMA
LMA-STM Silicone
LMA-STM silicone requirements refer to the specifications for silicone materials used in aerospace applications, particularly for Lockheed Martin Aeronautics (LMA). These materials are specified to meet the requirements of specific Lockheed Martin material and process specifications (STM).
While the exact details for a specific part would be found in the manufacturer’s official specifications, the requirements generally cover material properties, certification, and processing to ensure performance in demanding aerospace environments.
