Core Characteristics
Hydrophilic Surface Chemistry：Unlike standard hydrophobic aerogels, Runhui offers hydrophilic powders with active silica surfaces-ideal for applications in water absorption, chromatography, and catalysis.
Ultra-High Specific Surface Area：Featuring nanoporous frameworks, these powders provide surface areas typically exceeding 700 m²/g, making them excellent adsorbents and catalyst carriers.
Fine Particle Size：Produced in well-graded micron-scale particles (~1–200 µm), Runhui's powder is easily dispersible in coatings, adhesives, and composite matrices.
Low Thermal Conductivity：Like typical silica aerogel, the powder offers superior thermal insulation properties, with packed thermal conductivity under 0.020–0.030 W/m·K, effective in thermal barrier formulations.
Flame-Retardant & Non-Toxic：As inorganic silica, it is non-flammable, chemically stable, and environmentally benign-suitable for fireproofing applications.
Versatile End Uses：Ideal for absorbents, insulating fillers, high-performance coatings, catalyst supports, chromatography media, and additive solutions in cosmetics, thermal slurries, paints, and adhesives.
Adsorbents & Dehumidifiers – For chromatography, moisture control, and air purification
Thermal Slurry Fillers – In high-temperature pipeline coatings or insulation composites
Catalyst Supports – High surface substrates for petrochemical and catalytic reactors
Specialty Coatings/Additives – In paints, adhesives, rubbers, and cosmetics for insulation or absorption functions
