AL2CHEM SPECIALTIES AL FS-200

AL FS-200 is the most widely used grade of fumed silica. Fumed silica’s unique manufacturing process produces a very high purity type of silica with nano size primary particles, a fluffy white powder that is an amorphous and colloidal form of silica. These characteristics impart a wide range of benefits to formulations from thickening and reinforcement to free flow and anti-settling.
