 SEALED P&D® Fumed Silica 

 

P&D® Fumed Silica  is a very fine amorphous silica manufactured using techniques developed by SEALED. 

P&D® Fumed Silica is a very fine amorphous silicon dioxide made from highly purified chlorosilanes via combustion with oxygen and hydrogen. 

P&D® Fumed Silica  has numerous applications due to its remarkable properties, including high purity, excellen dispersion, enormous surface area, and extremely fine particle size. These characteristics offer advantages for use in a wide range of products such as silicone rubber, sealants, organic elastomers, coatings, printing inks, adheves and materials used to improve flow characteristics.
