AEROXIDE® STX 501 - Hydrophobic Fumed Silican-titanium Mixed Dioxide
Evonik Industries, one of the world's leading specialty chemicals companies.
AEROXIDE® STX 501 is a hydrophobized fumed silicon-titanium mixed oxide with a titanium dioxide core and a silica shell. It combines the triboelectrical charge attributes of titanium dioxide with the surface properties of a silica. Its high hydrophobicity is imparted by trimethylsilyl-groups which are firmly anchored to the silica surface.
