Cabot's Fumed Metal Oxides (FMO) business is made up of two product families:

• Fumed Silica (includes CAB-O-SIL® untreated and treated): CAB-O-SIL fumed silicas are free-flowing powdered products available in untreated and treated grades. They are very versatile and used in a variety of applications, ranging from spark plugs and printing inks to pharmaceuticals and cake mixes. CAB-O-SIL's versatility is related to its high degree of purity and amorphous structure, both of which lead to excellent performance.
  
  
• Fumed Alumina (includes SpectrAl® Fumed Aluminas, untreated and treated): These products are unique because of their unusual particle characteristics, crystallinity and high purity. In powder form, fumed alumina is fine, white, and extremely fluffy. However, when finely dispersed in liquids and polymers, it appears colorless and clear. SpectrAl fumed alumina enhances several different properties in a formulation, such as hardness and positive charge.

 

All of these products are primarily used to:

• improve flow properties of powdered product
• provide rheology control for liquids
• control sag of liquids (thixotropy)
• reduce caking of powders in storage
• prevent waxy products from congealing
• serve as a dry carrier for liquids and as emulsification agents
• act as a grinding agent
• allow encapsulation of flavoring oils
• serve as a reinforcing filler in elastomers
  
  

The FMO product lines also include CAB-O-SPERSE®, CAB-O-SIL® TG and SpectrAl® TG. Additionally, we offer specialty additives for Toners that include: CAB-O-SIL® TG treated fumed silicas, SpectrAl® TG treated fumed alumina, and CAB-O-SIL™ TG-C treated colloidal silicas.
