Graphene Nanoplatelets (GNPs)
Our graphene nanoplatelets (GNPs) are useful as nano-additives for advanced composites, as a component in advanced batteries and ultracapacitors, as the conductive component in specialty coatings or adhesives, and as a component of e-inks or printable electronic circuits.
Other applications include exceptionally strong and impermeable packaging, better lubricants, and a recent publication even demonstrates that our conductive graphene nano-platelets, surface-treated with sensitized molecules, can be used to produce highly sensitive bio-sensors.
Our GNPs consist of several sheets of graphene with an overall thickness of approximately 3-10 nanometers depending on the specific product. Grade 4 GNPs are <3nm thick.

Graphene Nanoplatelets (GNPs)
Grades 3-4
Please Note- Grade 1 & 2 have been discontinued. We anticipate releasing new GNP products in the near future.
Our current GNP materials come in two “grades” and sizes:
Grade 3 is Industrial Grade.
Grade 4 is Research Grade and can be Functionalized with a wide variety of Functional Groups.
1. Grade 3, which has surface areas 600 – 750 m2/g, 4-5 layers, an average thickness of 8nm, and typical particle diameters of less than 2 microns. This material is very good for applications requiring high capacitance.2. Grade 4, Research Grade HDPlas - >700m2/g, <3 layers, <3nm thick. >2000m2/g surface areas have been measured using experimental NMR. This material is highly crystalline. It is available in neat, OH, CO, COOH, or primarily NH2 functional groups. Other functionalities are available. This product can already be produced in multiple KGs per day and the capacity is growing.
Cheap Tubes Inc is the primary supplier of HDPlas products to the R&D community worldwide and the sole and excusive agent in North America.
Please Note- All HDPlas Products prices are for R&D quantities. Commercial Quantities are available. Please contact us for commercial pricing.
