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

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 discretion. 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.

• 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

Vespel® PI insulators and sockets

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

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

Protective housings in Torlon® or 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 or PI :

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

Our workshops are secure, our material flows are controlled and each part undergoes a final inspection. Whether for confidential prototypes, critical small series or embedded systems, we guarantee performance, responsiveness and confidentiality.
