Graphene Nanoplatelets (GNP-01)

Description

1. Product Overview

Graphene Nanoplatelets (GNP-01) are high-purity, few-layer graphene stacks engineered for macroscopic reinforcement of composites, coatings, and energy storage systems. Primary industrial applications include lightweight structural composites for automotive and aerospace, anti-corrosion and thermal management coatings, and next-generation Li-ion battery anodes. The key value proposition is a 30–40% improvement in mechanical strength and electrical conductivity at less than 2 wt.% loading, enabling dramatic material performance gains without production line overhauls. Strategically, GNP-01 addresses the critical market need for scalable, cost-effective 2D materials that bridge the gap between lab-grade graphene and industrial throughput.

2. Key Specifications & Technical Characteristics

• Chemical composition: Few-layer graphene nanoplatelets (C > 99.5%), oxygen content < 2.5%

• Purity grade: Industrial premium grade (carbon basis, ash < 0.1 wt.%)

• Physical characteristics:

  • Form: Black superfine powder

  • Average lateral platelet size (D50): 5–10 µm

  • Average thickness: 4–8 nm (approx. 12–20 layers)

  • Specific surface area (BET): 120–180 m²/g

  • Tap density: 0.10–0.15 g/cm³

  • Electrical conductivity (compressed pellet): > 10,000 S/m

• Packaging options: 100 g, 1 kg, 5 kg vacuum-sealed foil bags; 25 kg fiber drums with inner PE liner; custom bulk IBC totes

• Shelf life: 24 months when stored in sealed, dry conditions (RH < 40%, 15–25°C)

3. Core Industrial Applications

• Primary industries: Advanced composites, functional coatings, automotive, aerospace, energy storage, thermal interface materials

• Operational use cases:

  • Structural composites: 1.5–2 wt.% GNP-01 in epoxy increases flexural modulus by 35% and reduces water vapor transmission rate by 60% compared to carbon black or CNT alternatives.

  • Anti-corrosion coatings: 0.5–1 wt.% dispersed in polyurethane or epoxy primers achieves salt spray resistance > 1,000 hours (ASTM B117) — outperforming zinc-rich primers at half the coating weight.

  • Li-ion anodes: 3–5 wt.% GNP-01 blended with graphite or LTO reduces charge transfer resistance by 40% and extends cycle life beyond 2,000 cycles.

• Why better than alternatives: Unlike multi-wall carbon nanotubes (MWCNTs), GNP-01 disperses with low shear mixing (no high-energy sonication required) and achieves percolation thresholds below 1.5 vol.%, lowering raw material cost by 60–70% relative to CNTs for equivalent conductivity.

4. Competitive Advantages

• Quality consistency: Lot-to-lot CV < 5% for thickness, lateral size, and carbon purity; each batch validated by Raman (I₂D/I<1.5) and TGA.

• Supply reliability: Manufacturing capacity of 120 MT/year across three ISO 9001:2025-certified lines; safety stock held in regional hubs (North America, EU, Asia).

• Logistics capability: Express air freight (5–7 days) for R&D quantities; sea freight (20–25 days) for commercial volumes with UN-certified non-hazardous classification (not listed as dangerous goods under IATA/IMDG).

• Price competitiveness: Volume pricing from $0.80–1.20 per gram (1 kg+) — 50–70% lower than lab-grade graphene oxide or few-layer pristine graphene.

• Sustainability: Produced via solvent-free electrochemical exfoliation with 85% less water and 40% lower carbon footprint than Hummers’ method; full EPD available on request.

• Technical support: Free dispersion protocol library (water, epoxy, NMP, DMF); dedicated application engineer assigned per corporate account; CoA, SDS, and XRD/Raman files embedded in every shipment.
