Powderhik
High Performance Silica Aerogel Powder
Powderhik is a high-purity, nanoporous silica aerogel powder known as the “lightest solid” additive for advanced insulation applications. Featuring an extraordinarily high specific surface area and ultra-low thermal conductivity, it serves as a critical performance enhancer for thermal insulation coatings, plasters, textiles, and composite materials.
Designed for high versatility, Powderhik is easily dispersed into various solvent-based or water-based systems. It significantly boosts thermal insulation and fire resistance without altering the volume or adding significant weight to the base material.
