High-performance polymers for defense: reliability, durability, discretion

High-performance polymers for defense: reliability, durability, discretion

Defense and technology: extreme requirements for critical environments

Military applications require components capable of withstanding extreme conditions: very high or very low temperatures, corrosive environments, intense mechanical stress and the need for electromagnetic stealth. In this context, high-performance polymers (HPP) offer a strategic alternative to metals, combining robustness, lightness and adaptability.

DEMGY designs and manufactures HPP plastic parts for the land, naval, air and space sectors, within a strict framework of confidentiality, traceability and compliance with military standards.

Why choose HPP plastics for defense?

  • Extreme thermal, chemical and mechanical resistance
  • Electrical insulation and compatibility with sensitive equipment
  • Lightweight compared to metal alloys
  • Complex shapes possible (machining, molding, 3D printing)
  • ISO 9001 / EN 9100 certified production with rigorous inspection

Examples of specific applications:

Vespel® PI insulators and sockets

For military electronic systems, electromagnetic stealth is paramount. Vespel® provides:

  • reliable electrical insulation
  • dimensional stability
  • thermal resistance without outgassing

Protective housings in Torlon® and PEEK GF

Used for shielding sensors or electronic boards:

  • high mechanical and chemical resistance
  • excellent wear resistance
  • lightness and durability

Optical and mechatronic components

Machined from bars or plates of LCP, PCTFE and PI:

  • internal structures for tactical optics
  • UAV parts and sighting systems
  • lens or sensor mounts
