High-performance polymers for nuclear applications: safety, strength and durability

The nuclear sector: an extreme, regulated environment

The nuclear sector - whether civil or military - requires materials that can withstand ionizing radiation, heat, chemical agents and severe thermal cycles. High-performance polymers (HPP) are effective replacements for metals or ceramics in critical functions such as insulation, support, sealing and guidance.

DEMGY designs and produces custom HPP parts for nuclear operators, laboratories, equipment manufacturers and maintenance in controlled areas. Our mastery of processes guarantees traceability, conformity and safety.

Advantages of HPPs in nuclear environments

Excellent resistance to radiation and corrosion
Thermal (up to 260°C) and mechanical stability
Low outgassing and compatibility with irradiated areas
Precision machining and molding for critical components
Rigorous quality control and certification (ISO 9001 / EN 9100)

Examples of nuclear applications

PVDF or PPS sheaths and insulators

Cable and sensor protection in irradiated areas
Outstanding chemical resistance
Radiation stability

Mechanical components in PEEK or PTFE

High-strength guides, bushings and slides
Low friction, long service life
Resistance to severe thermal cycles

Parts for robotics and nuclear maintenance

Manipulator arms, inspection elements
