Aerogel

When evaluating Aerogel, the most critical factor is its Thermal Conductivity, which typically ranges from 0.015 to 0.025 W/(m·K). You must also verify the Hydrophobicity rate (ideally ≥99%) to ensure performance in humid environments. For industrial applications, check the Density (usually 160-220 kg/m³ for blankets) and Temperature Resistance limits, which can range from -200°C up to 650°C or 1000°C depending on whether it is silica or carbon-based.

B2B buyers should prioritize suppliers with ISO 9001 for quality management and ISO 14001 for environmental standards. For construction and industrial safety, ensure the product has a Class A1 Non-combustibility rating (EN 13501-1) and ASTM C1728 compliance for flexible aerogel insulation. Always request a Material Safety Data Sheet (MSDS) and RoHS/REACH certifications to confirm the absence of hazardous substances.

Aerogel is primarily sourced in three forms: Aerogel Blankets (best for pipe insulation and construction), Aerogel Panels (ideal for high-end appliances and EV battery thermal runaway protection), and Aerogel Particles/Powders (used as additives in coatings or translucent skylights). For the Electric Vehicle (EV) sector, focus on ultra-thin blankets that provide fire barriers between battery cells.

Request a Third-party Lab Test Report (such as SGS or TUV) focusing on tensile strength and dust release levels. High-quality aerogel should have minimal 'powdering' effect. Conduct a water immersion test on samples to verify hydrophobicity and check for thickness consistency across the roll, as variations can lead to thermal bridging in industrial installations.

The main risk is Physical Damage and Compression during transit; if aerogel blankets are compressed under heavy cargo, their nanoporous structure can collapse, permanently reducing insulation value. Ensure the supplier uses reinforced pallet packaging and clearly labels the cargo as 'Do Not Stack'. Additionally, be aware of Customs HS Code classification (typically under Chapter 68), as incorrect coding can lead to significant duty penalties.

Aerogel is a high-value commodity. Negotiate based on Total Square Meters (SQM) rather than weight. For long-term projects, seek a tiered pricing structure where costs drop by 10-20% as volume exceeds 5,000 SQM. For new buyers, suggest a Paid Sample Order first; many top-tier suppliers on Made-in-China.com will credit the sample cost back to your first bulk order.

Due to its ultra-lightweight but high-volume nature, Aerogel is often billed by Volumetric Weight. For large orders, FCL (Full Container Load) is highly recommended to prevent contamination from other goods and to optimize shipping costs. Ensure the Incoterms are clearly defined; FOB (Free On Board) is preferred for buyers who have their own freight forwarders to manage the delicate handling requirements.

Always utilize the Secured Trading services provided by Made-in-China.com to protect your payments. Never transfer full payments upfront to unverified accounts. Use Letter of Credit (L/C) for very large industrial contracts or Telegraphic Transfer (T/T) with a 30% deposit and 70% balance against the Bill of Lading (B/L) after a successful Pre-shipment Inspection.
