High-performance elastomers and composites for defence and armaments
As a key strategic partner in French industrial innovation, BORFLEX® designs bespoke, high-tech solutions for the critical nuclear and defence sectors. With over 65 years’ expertise in the formulation, prototyping and processing of elastomers and composites, we put our know-how at the service of the three armed forces and the special forces as a member of the BITD.

Defence and land-based armaments
Ensure the equipment is resilient and completely watertight in the face of the challenges posed by the terrain
We design components that are essential for maintaining the integrity of armoured vehicles and ground-based weapon systems, absorbing impacts whilst ensuring minimal operational maintenance.
- Articulated protective bellows
- Seals for hatches, turrets, windows and filters
- Radar shields and on-board protective panels
- Technical crampons

RESPONSE TO OPERATIONAL CONSTRAINTS RELATING TO DRONES
(AIR, LAND, SEA)
BORFLEX® develops bespoke components made from high-performance elastomers and composites:
- Sealing & Protection (IP5X/IP6X): profiled
seals, closed-cell foam and filters that are resistant to water, splashes and dust. - Acoustic stealth: bespoke sound
insulation and anti-vibration mounts to reduce acoustic signature (particularly for maritime and stealth drones). - Weight optimisation: lightweight fibreglass
composites and structural foams to reduce the aircraft’s weight without compromising strength. - Resistance to extreme temperatures (-60 °C to +250 °C):
silicones and thermal insulators that ensure consistent motor performance, even in Arctic conditions.


DOMESTIC SECURITY FORCES & SPECIAL FORCES
Robust equipment that is ready for immediate use
We provide reliable solutions for emergency response and public safety units, focused on the physical protection of personnel and the minimisation of tactical signatures.
- Personal protective equipment and elastomeric shields
- Soundproofing and impact noise reduction solutions
- Bespoke technical spare parts for specific weapon systems
Nuclear safety
FLEXIBORE®: Innovation in Radiation Protection
To meet the needs of the nuclear defence sector (deterrence, naval propulsion) and the civil sector, BORFLEX® has developed its exclusive FLEXIBORE® technology.
Formulated using boron carbide (B₄C), the FLEXIBORE® range offers highly effective absorption of thermal neutrons, thereby protecting people and sensitive equipment.
Security guarantees:
Our products are manufactured at a dedicated industrial site (Cherbourg), ensuring full traceability. We are certified to EN ISO 19443 and qualified to supply components that are Important for Nuclear Safety (IPSN).
