What is GNP YXL-GP15?
GNP YXL-GP15
YXL-GP15 is a physically exfoliated graphene nanoplatelet powder for conductive and thermal material development.

What It Is Not
- GNP means graphene nanoplatelets, not graphene oxide, reduced graphene oxide, or graphite powder.
When Not to Use It
- Do not use GNP when transparency, electrical insulation, or a strongly isotropic conductive network is required and platelet orientation cannot be controlled.
Intrinsic Screening Summary
- Identity screen
- Graphitic carbon; Platelet carbon
- Intrinsic feature
- The thin platelet structure supports graphitic conductive and thermal pathways. YXL-GP15 uses a dispersion/intercalation-aid approach intended to suppress secondary stacking and support dispersion in pure water, polar solvents, and polymer matrices; this is a grade-specific processing aid, not a claim of unconditional dispersion stability.
- Material-level integration
- Add in batches with a suitable dispersant; pre-soak with dispersant for at least half a day before use; use high-speed shear or emulsification equipment for slurry dispersion. Dispersion and composite performance depend on the recommended dispersant, pre-soaking, shear or emulsification conditions, concentration, and host system. The powder absorbs moisture: keep sealed and dry before use if needed, and qualify the selected formulation and process.

|---|---|---|
| Physically exfoliated graphene nanoplatelet powder; grey-black platelets; <10 layers (typical 3-7) | GNP supports Conductive Materials, EMI Shielding Materials, Heat Dissipation, ESD Materials, Energy Storage, Carbon Dispersion. | The thin platelet structure supports graphitic conductive and thermal pathways.

Compare Material Routes
| Material / Route | Decision Boundary |
|---|---|
| MWCNT | GNP provides a platelet-network route that can support heat spreading and conductivity when exfoliation and alignment are controlled. MWCNT network systems and GNP platelet systems have different dispersion, geometry, orientation, restacking, shear-history, viscosity, and loading sensitivities. Compare them in the same host formulation, processing route, geometry, direction, conditioning, and test method; neither route is a universal winner. |

FAQ
How does the supplied YXL-GP15 dispersion approach differ from untreated GNP?
YXL-GP15 uses a dispersion/intercalation-aid approach intended to suppress secondary stacking and support dispersion in pure water, polar solvents, and polymer matrices. The result still depends on the recommended dispersant, pre-soaking, shear or emulsification conditions, concentration, and host system.
What does the stated 3-7-layer value represent?
The YXL-GP15 grade specification reports fewer than 10 graphene layers, with a typical value of 3-7 layers, characterized by SEM and Raman spectroscopy. It is a grade-specific characterization value, not a universal definition for all GNP materials.
Which conditions should be fixed when qualifying YXL-GP15 dispersion and composite performance?
Fix and record the host system, formulation and concentration, recommended dispersant, pre-soak time, shear or emulsification equipment and conditions, moisture handling, sample geometry, conditioning, and test method before comparing results.
