Carbon Nanotubes

Description

1. Product Overview
Carbon Nanotubes are cylindrical macromolecules composed of sp²-hybridized carbon atoms, exhibiting exceptional electrical, thermal, and mechanical properties. Their primary industrial use lies in advanced composites, battery electrodes, conductive coatings, and semiconductor components, delivering order-of-magnitude improvements in strength-to-weight ratio and conductivity over conventional materials. The key value proposition is enabling next-generation lightweighting and energy efficiency gains across automotive, aerospace, and electronics sectors. Strategically, CNTs are a critical enabler for the global transition to high-performance electric vehicle batteries and structural smart materials.

2. Key Specifications & Technical Characteristics

• Chemical composition: ≥99.5% carbon (multi-walled or single-walled, as specified)

• Purity level: Up to 99.9% (ash content <0.1%)

• Physical characteristics: Black fibrous powder; outer diameter 5–20 nm (MWCNT) or 0.8–2 nm (SWCNT); length 5–30 µm; bulk density 0.03–0.15 g/cm³

• Packaging options: 100 g, 500 g, 1 kg vacuum-sealed foil bags; 10 kg and 25 kg fiber drums with moisture-barrier liners

• Shelf life: 24 months when stored in sealed, dry, ambient conditions (15–30°C)

3. Core Industrial Applications

• Lithium-ion batteries (EV & consumer electronics): Used as conductive additive (0.5–1.5 wt%) in anodes – reduces internal resistance by 40% versus carbon black, enabling faster charging and higher cycle life.

• Advanced composites (aerospace & automotive): Incorporated into epoxy or thermoplastics – increases tensile strength by 200% at only 1–3% loading, replacing heavier metal reinforcements.

• Electrostatic dissipative (ESD) coatings: Applied in cleanroom flooring and fuel system components – provides permanent conductivity without carbon powder shedding, outperforming carbon fiber in thin-film uniformity.

4. Competitive Advantages

• Quality consistency: Lot-to-lot CV <3% for diameter and purity, verified by third-party Raman and TGA.

• Supply reliability: Dedicated production lines with 50 MT annual capacity; safety stock held in three regional hubs.

• Logistics capability: Expedited air freight (5 days) or sea freight (20–25 days) with hazardous material certification.

• Price competitiveness: Tier-1 pricing at 15–20% below European and US equivalents for equivalent or higher purity.

• Sustainability: Manufactured via catalytic CVD with >90% precursor gas recycling; documentation available for REACH and RoHS compliance.

5. Commercial & Supply Information

• Minimum Order Quantity (MOQ): 1 kg (sample grade); 25 kg (commercial grade)
