Our defence product portfolio
We offer a broad portfolio of materials that support various defence applications:
- Flame retardant materials
Flame retardant additives and compounds are used to enhance fire safety in critical defence systems. These materials are applied in engineering plastics, cable systems, electronic housings, and vehicle components to reduce flame spread and improve resistance to high temperatures. They play a key role in protecting both equipment and personnel in confined and high-risk environments.
- Ethylcellulose
Ethylcellulose is used in specialized defence applications as a binder and film-forming material. It is applied in combustion-control systems such as propellant coatings, as well as in protective coatings for sensitive components. Its chemical stability and controlled performance make it suitable for precision applications.
- High-performance resins and composites
Our portfolio of epoxy resins, bismaleimide, and vinyl esters is used in structural and composite applications where strength, durability, and heat resistance are required. These materials are commonly found in aerospace structures, naval components, and lightweight vehicle parts, where they contribute to corrosion resistance, mechanical strength, and reduced weight.
- Functional plastic compounds
We offer advanced compounds engineered to provide electrical protection, thermal control, and functional performance in defence systems:
- EMI / RFI shielding compounds – used to protect electronic systems such as radar, communication equipment, and avionics from electromagnetic interference
- Conductive and anti-static compounds – prevent electrostatic discharge and ensure the safe operation of sensitive electronics
- Static dissipative materials – enable controlled discharge of electrical energy in housings and packaging
- Thermal management compounds – support heat dissipation in electronics, UAV systems, and high-density components
- Light-controlling compounds – used for optical performance, light diffusion, and stealth-related applications
- Flame retardant compounds – provide fire protection in electrical systems and enclosures
- High-density and recycled compounds – support weight balancing, vibration damping, and sustainable material solutions in engineering applications
Key performance features in defence applications
Materials used in defence environments must meet strict technical requirements. Our solutions are designed to deliver:
- Lightweight performance for improved mobility and system efficiency
- Corrosion and wear resistance in harsh and marine environments
- Heat resistance and flame retardancy for safety and durability
- Structural strength and reinforcement in load-bearing components
- Stealth and optical control properties for advanced systems
- Electrical protection, including EMI/RFI shielding and static control
These features are essential in applications such as UAVs, military vehicles, radar systems, electronics, and aerospace components.
