Description

Graphene Nanoplatelets (GNPs) are ultra-thin, two-dimensional carbon nanomaterials composed of several layers of graphene stacked into plate-like structures. With exceptional electrical, thermal, mechanical, and barrier properties, GNPs serve as a next-generation additive for high-performance composites, coatings, elastomers, polymers, energy devices, and functional materials.

Engineered through advanced exfoliation and purification processes, our GNPs offer controlled thickness (1–10 nm), high lateral dimensions (0.5–20 µm), and extremely high aspect ratios, enabling outstanding reinforcement efficiency even at low loading levels. Their unique conjugated sp²-hybridized carbon structure provides superior electron mobility, excellent mechanical strength, and remarkable chemical stability, making them ideal for demanding industrial and research applications.
