    Superfine white carbon black (ultrafine white carbon black)
     
    Superfine white carbon black (ultrafine white carbon black) is a white, non-toxic, tasteless and amorphous inorganic fine chemical product, which is made through chlorosilane’s hydrolysis process in high temperature oxyhydrogen flame. By adjusting the process conditions, silica powder’s primary particle size can be produced as 7-40 nanometer, and the specific surface area of the product can be 50-400m2/g.
    Since ultrafine silica has the features of small particle size, large surface area, high surface activity properties, the product is widely used in rubber, coating, adhesive, paint, printing ink, plastics, cosmetics, agriculture, medicine and other fields. It has various functions such as good reinforcement, thickening, thixotropic, extinction, UV resistance, sterilization and etc.

    High transparency
    The high purity of this series of products ensures their refractive index to be consistent with the refractive index of resin.

    High heat dissipation
    Special production process to make this series of products, quickly spread to the other surface of the paint, to extend the life of the paint.

    High suspended property
    This series of products are produced through special treatment to both internal and external structures. Even after long-time placement, there will be no precipitation and stratification to the paint.

    High extinction
    Advanced production technology not only increases the pore volume of the product, but also ensures the consistency and evenness of particle clearance, which achieves a high extinction rate.

    High dispersion
    The series of products can easily disperse in any sorts of paint. Generally, they can be fully dispersed after 10 minutes of mixing with 10 - 20M/S linear velocity and using regular high speed mixer.
