grace.com Ease of Handling and Dispersion The higher density of Syloid® silicas, when compared to many fumed (colloidal) silicas, makes it easier to handle, results in less dust for a cleaner production environment
Densified silica fume: particle sizes and dispersion in ...
Fumed silica (CAS number 112945-52-5), also known as pyrogenic silica because it is produced in a flame, consists of microscopic droplets of amorphous silica fused into branched, chainlike, three-dimensional secondary particles which then agglomerate into tertiary particles.
HDK ® pyrogenic silica is a mature product produced by WACKER for over 40 years and used by customers worldwide with great success. Due to our integrated production system with its statistical process control and highly efficient reactor dynamics, the pyrogenic silica we produce is exceptionally pure.
AERODISP ® W 1244 is a fumed silica dispersion with very high silica content, specifically developed for the application fire resistant glass. It is tailored to simplify the fire resistant glass manufacturing process and provides outstanding optical and fire test performance of the final glass.
