A single atom-thick layer of carbon with extraordinary electrical, thermal and mechanical properties. Our graphene is derived from premium Sri Lankan vein graphite — the world's highest-purity natural graphite source — ensuring exceptional feedstock quality and reproducible graphene performance.
The quality of graphene oxide and reduced graphene oxide is directly constrained by feedstock purity. Lower-grade graphite introduces metallic impurities — particularly Fe, Mn and Al from the Hummers oxidation process — that degrade the final GO/rGO product. Starting from G-99.5 Sri Lankan vein graphite gives a cleaner oxidation reaction, more reproducible exfoliation, and higher-quality graphene with fewer process contaminants.
Stacked few-layer graphene with lateral dimensions of 1–25 µm. Cost-effective for composite reinforcement, conductive coatings, and thermal management applications where cost-performance ratio is critical.
Single and few-layer graphene functionalised with oxygen groups (–OH, –COOH, epoxide). Dispersible in water and polar solvents. Ideal for filtration membranes, biomedical research and functionalised composite applications.
Chemically or thermally reduced GO with partially restored conductivity. The practical graphene for most industrial applications — conductive, dispersible and scalable to production quantities.
