BMS 1-74 Silicone

BMS 1-74  silicone from ElastaPro meets Boeing Material Specifications (BMS). Choose these specification grade silicone materials as solid silicone sheet or uncured silicone compound in the durometers, sizes, and colors that you need. ElastaPro is AS9100D and ISO 9001:2015 certified.

What is BMS 1-74 Silicone?

BMS 1-74 is a high-performance silicone rubber specified by Boeing for use in aerospace seals and gaskets. It is a synthetic, durable material known for its flexibility across a wide temperature range, resistance to environmental factors, and suitability for sealing gaps and joints.
  • Material: Synthetic silicone rubber
  • Purpose: Primarily used for seals and gaskets in aircraft that require flexibility and durability in a wide temperature range.
  • Key properties:
    • High flexibility
    • Durable
    • Resistant to environmental factors
    • Provides reliable sealing against moisture, chemicals, and extreme temperatures 

BMS 1-74 Silicone Sheet

BMS 1-74 silicone sheets are engineered to meet stringent standards for flexibility, durability, and high resistance to environmental factors. At ElastaPro Silicone Sheeting, these sheets arrive ready for die-cutting. They are between 0.010” and 0.500” thick and available in widths of up to 60”.

BMS 1-74 Silicone Compound

This BMS standard sets stringent standards for the chemical composition and physical properties of uncured silicone compounds. This ensures that materials meet the specific requirements for aerospace use. By adhering to BMS, manufacturers guarantee that the compounds contribute to producing high-quality and durable aviation components.
