Boron Nitride Powder (BNP-03)

Description

1. Product Overview

Boron Nitride Powder (BNP-03) is a high-purity, hexagonal boron nitride (h-BN) engineered for extreme thermal management and electrical insulation in advanced industrial systems. It is primarily used as a functional additive in thermal interface materials, high-temperature release agents, and ceramic composites. The key value proposition lies in its unique combination of high thermal conductivity (≥30 W/mK), dielectric strength, and lubricity up to 900°C in oxidizing atmospheres. Strategically, BNP-03 addresses the critical market need for lightweight, chemically inert thermal solutions in EV power electronics, aerospace, and 5G semiconductor packaging—where legacy materials like alumina or aluminum nitride fall short in either insulation or high-temperature stability.

2. Key Specifications & Technical Characteristics

• Chemical composition: Hexagonal Boron Nitride (h-BN), >99.5% purity (no amorphous boron or B₂O₃ impurities)

• Crystal form: Hexagonal platelet (turbostratic-free, fully crystallized)

• Appearance: White, odorless, free-flowing powder

• Particle size distribution: D50 = 3.0 – 5.0 µm (unimodal), D90 ≤ 10 µm

• Specific surface area (BET): 8 – 12 m²/g

• Tap density: 0.25 – 0.35 g/cm³

• Thermal conductivity (in-plane): ≥300 W/mK; (through-plane in composites): ≥30 W/mK

• Maximum use temperature: 900°C (air), 2,800°C (inert atmosphere)

• Volume resistivity: >10¹⁴ Ω·cm at 25°C

• Packaging options: 1 kg vacuum-sealed aluminum foil bags; 20 kg multi-wall paper bags with PE liner; 200 kg steel drums with desiccant

• Shelf life: 24 months from date of manufacture when stored in original sealed packaging in dry, ambient conditions (10–35°C, ≤60% RH)

3. Core Industrial Applications

• Electric vehicle power modules (EV/HEV): Used as a thermally conductive, electrically insulating filler in silicone gap pads and potting compounds. BNP-03 outperforms spherical alumina by enabling lower viscosity at high loadings (70–80 wt%), reducing pump wear and allowing thinner bond lines for lower thermal resistance.

• Aerospace & defense coatings: As a high-temperature release agent for composite layup molds (autoclave curing at 400–800°C). Unlike graphite-based releases, BNP-03 leaves zero carbon residue, eliminating post-cure cleaning and contamination risks on CFRP parts.

• Semiconductor packaging (advanced substrates): Added to epoxy molding compounds (EMCs) for 5G mmWave devices. Its low dielectric constant (ε = 3.9 at 10 GHz) and low loss tangent (tan δ < 0.001) preserve signal integrity—critical where fused silica or alumina would introduce excessive signal attenuation.

• Continuous casting of non-ferrous metals: As a powder lubricant for aluminum and copper billet casting. BNP-03 reduces die friction by 40% vs. oil-based lubricants, extends die life 3×, and eliminates smoke/fume hazards, lowering workplace ventilation costs.

4. Competitive Advantages

• Quality consistency: Lot-to-lot Cpk ≥ 1.33 for D50 and BET; each batch certified via XRD (no c-BN or turbostratic phase) and TGA (oxidation onset ≥ 900°C). Full CoA (Certificate of Analysis) with ICP-OES trace metals (<50 ppm Fe, <20 ppm Ca).

• Supply reliability: Two geographically redundant production lines (Asia, Europe) with 50-ton monthly capacity buffer. Safety stock held in three regional warehouses (NA, EU, APAC) to mitigate geopolitical or logistics disruptions.

• Logistics capability: EXW, FOB, CIF, DDP terms available. Dangerous goods classification: Not regulated (non-hazardous under IMDG, IATA, ADR).

• Price competitiveness: Cost per effective thermal unit (W/mK per $/kg) is 20–30% lower than comparable h-BN grades from Momentive (PT Series) or Saint-Gobain (CarboTherm). Volume pricing passes supply chain automation savings to buyers.

• Sustainability & compliance: Manufactured via boric acid + melamine route with 92% nitrogen recycling; RoHS, REACH, TSCA compliant. Zero SVHC, no conflict minerals.

• Technical support: Dedicated application engineers available for rheology optimization, composite mixing protocols, and particle size customization (down to D50 0.5 µm or up to 50 µm on request).

5. Commercial & Supply Information
