Graphene nanoplatelets are integrated directly into standard industrial polymers, delivering consistent electromagnetic shielding and electrical conductivity across high-frequency ranges, without metallic additives, without process overhaul. G-Shield™ is a product line of graphene-based polymer compounds, currently available in PP and PVC bases, built to replace conventional metal shielding with a lighter, processable, and equally effective alternative. Lighter. More flexible. Easier to manufacture. The same shielding performance at a fraction of the weight, fully compatible with extrusion, injection moulding, and 3D printing workflows, and scalable within existing production lines. Suited for cables, electronics packaging, and advanced mobility systems, G-Shield positions graphene as a practical, ready-to-use industrial-grade solution for today's high-performance products.
Hexa-Shield is a graphene-based conductive coating formulated for EMI shielding of complex geometries and surfaces. Applied by spray, brush, or bar coating, it provides controlled shielding effectiveness across a broad frequency range. Suitable for electronics enclosures, defence components and industrial substrates.
