: It is generally non-reactive, making it a safe additive for a variety of sensitive products. Industrial Applications
, which allows it to interact effectively with other substances.
: It provides structural reinforcement and controls flow during application. 112945
: Fumed silica has an incredibly high surface area-to-mass ratio, typically ranging from
Because of its unique ability to thicken and reinforce, fumed silica is used in a vast array of consumer and industrial goods: : It is generally non-reactive, making it a
While fumed silica is not classified as a carcinogen, it is an due to its fine particle size. Prolonged or high-level exposure can irritate the respiratory system and eyes. Consequently, safety protocols typically require the use of protective masks and ventilation when handling the dry powder in industrial settings. CAS 112945-52-5: Silica, amorphous, fumed, cryst.-free
The number is the primary CAS registry number for fumed silica (also known as pyrogenic silica), a versatile synthetic material used extensively across modern industry. The Science of Fumed Silica : Fumed silica has an incredibly high surface
: One of its most valued traits is its ability to change the viscosity of liquids. It creates a "thixotropic" effect—liquids become thinner when stirred or agitated but thicken back into a gel-like state when left still.
