Overview
Synrock's Silica Aerogel Powder is manufactured through supercritical drying of silica sol-gel, producing an ultra-light, nano-porous material with the lowest thermal conductivity of any solid insulator currently available. With a porosity exceeding 95% and a surface area up to 800 m²/g, it delivers outstanding insulation performance in an extremely lightweight form.
The powder can be used as a functional additive or stand-alone insulation medium across a broad range of applications — from thermal interface materials and insulating paints to aerospace composites and cryogenic insulation systems.
Key Features
- Thermal conductivity as low as 0.018 W/m·K at ambient conditions
- Bulk density: 20~100 kg/m³ (grades available)
- Specific surface area: up to 800 m²/g (BET)
- Hydrophobic surface treatment — excellent moisture resistance
- Operating temperature range: -200 °C to +650 °C
- Non-toxic, halogen-free, compliant with RoHS/REACH
- Particle size: D90 customizable from 10–100 µm
Applications
- Aerogel insulation coatings and architectural paints
- Vacuum insulated panels (VIP) core filler
- Polymer composites and foam enhancement
- Cryogenic insulation systems (LNG, hydrogen storage)
- Thermal interface materials for electronics
- Textile and footwear thermal insulation
- Oil & gas pipeline anti-condensation coatings
