LMA Aerospace Silicone Sheet & Compounds (LMA-ME025 & LMA-STM)
ElastaPro is an AS9100D and ISO 9001:2015 certified manufacturer of specification-grade silicone sheeting and uncured compounds. We support defense and aerospace supply chains with high-performance elastomeric materials manufactured to meet strict aerospace quality standards, including Lockheed Martin Aeronautics LMA-ME025 and LMA-STM requirements.
Because LMA specifications are proprietary, ElastaPro maintains the rigorous manufacturing controls, raw material traceability, and clean-room processing necessary to align with qualified supplier procedures.

High-Performance Silicone for Critical Aerospace Applications
Aerospace and defense subcontracts demand materials capable of withstanding extreme environmental stressors while maintaining physical integrity. ElastaPro’s specification-grade silicone is engineered to provide superior sealing, thermal management, and environmental insulation for advanced defense systems.
Key Performance Characteristics:
-
Extreme Temperature Resistance: Maintains mechanical flexibility and sealing efficiency across an operational range of -80°F to +500°F (-62°C to +260°C).
-
Low Compression Set: Ensures critical seals, gaskets, and interfaces maintain their shape and sealing force during long-term exposure to mechanical stress.
-
Environmental and Fluid Resistance: Exceptional stability when exposed to ultraviolet (UV) light, ozone, moisture, severe weather, and specialized aerospace fluids.
-
Outgassing Control: Select formulations can be processed to satisfy strict aerospace outgassing requirements for vacuum and high-altitude environments.
Material Capabilities and Delivery Formats
To accommodate diverse manufacturing requirements, ElastaPro supplies LMA-compliant silicone in both cured, ready-to-die-cut sheeting and uncured compounds for custom molding or calendering operations.
