Features Of DOWSIL VM-2270 Aerogel Fine Particles

  1. Ultra-low thermal conductivity for superior insulation performance in thin-film applications.

  2. Nanoscale particle size distribution (< 50 nm primary particles) enabling uniform dispersion in polymer matrices.

  3. Hydrophobic surface treatment ensures compatibility with organic resins and resistance to moisture ingress.

  4. High specific surface area (> 600 m²/g) enhances functional loading efficiency at low dosage levels.

  5. Non-toxic, non-fibrous, and silica-based — compliant with REACH and RoHS requirements.

Typical Applications Of DOWSIL VM-2270 Aerogel Fine Particles

  1. Thermal insulation additives in architectural coatings and energy-efficient facade systems.

  2. Performance enhancer in aerospace-grade composites requiring weight reduction and fire resistance.

  3. Functional filler in high-end automotive under-hood sealants and battery thermal management gels.

  4. Key ingredient in flame-retardant intumescent paints for passive fire protection of structural steel.
