Key commercial players driving the domestic market include:

• Graphene Square: Widely regarded as a global pioneer in bottom-up monolayer synthesis. Founded by Dr. Hong Byung-hee, a researcher renowned for scaling large-scale CVD graphene on copper foils, the company completed a mass-production facility in Pohang. Graphene Square utilizes an advanced, continuous roll-to-roll (R2R) thermal CVD machine layout to produce wide-area graphene sheets targeted at thermal heating elements, electromagnetic shielding, and smart glass systems.

• KB Element: A dominant force in the bulk powder segment. KB Element utilizes a proprietary, eco-friendly plasma exfoliation technique to manufacture non-oxidized few-layer graphene (FLG). By avoiding chemical oxidation, their material retains excellent electrical and thermal baselines, positioning them as an active supplier of anti-static films and display components for consumer tech giants.

• BestGraphene: This firm specializes in manufacturing highly customized, functionalized few-layer graphene additives and masterbatches. Their primary target areas include high-performance electrode binders for lithium batteries, heat-dissipating pastes, and structural composite materials.

The continuous evolution of these companies' production capacities and corporate relationships is vital for monitoring the market's trajectory.
