Fumed Silica For Thickening, Filler, Coating, Printing Inks     


Product Name:         Pyrogenic Silica / White Carbon Black /  Silicon Dioxide

Molecular formula:    SiO2

CAS No.:                      112945-52-5



Product Description:                 



  silicasilicon dioxide productsilica packagin



Nanoscale Fumed SiO2 (CAS number 112945-52-5), also known as pyrogenic silica because it is produced in a flame, consists of microscopic droplets of amorphous silica fused into branched, chainlike, three-dimensional secondary particles which then agglomerate into tertiary particles.

Nanoscale Fumed SiO2 can be divided into hydrophilic type and hydrophobic type in accordance with their different surface treatments.

Positive Properties:                                         


For Hydrophilic Nanoscale Fumed SiO2 

  • Optimum adjustment of rheology during processing
  • Reinforcement of silicone elastomers
  • Thickening of non-polar liquids
  • Free-flow of foodstuffs and industrial powders
  • High chemical purity
  • Excellent insulation properties, even at high temperatures
  • Conversion of liquids to powders, e.g. pharmaceuticals, cosmetics
  • Gelification of battery acids
  • Rheology control of greases and lubricants


 For Hydrophobic Nanoscale Fumed SiO2 

  • Optimum rheology during processing
  • Thickening of polar liquids, e.g. epoxy resins
  • Reinforcement of silicone elastomers
  • High levels of loading, e.g. molding compounds
  • Excellent water-repelling properties, leading to improved corrosion protection
  • Improvement of dielectric properties, e.g. in cable compounds
  • Free-flow of powders, e.g. in fire extinguishers
  • Increased scratch resistance, e.g. in paints and plastics






Nanoscale Fumed SiO2 serves as a universal thickening agent and an anticaking agent (free-flow agent) in powders. Like silica gel, it serves as a desiccant. It is used incosmetics for its light-diffusing properties. It is used as a light abrasive, in products like toothpaste. Other uses include filler in silicone elastomer and viscosity adjustment in paintscoatings, printing inks, adhesives and unsaturated polyester resins. It is also used in the production of cat litter box filler. 



S-150Fumed silica S-150 is mainly used for acidic silicone rubber, RTV silicone rubber (low moisture content) and neutral silicone rubber


S-200Fumed silica S-200 is mainly used for high-temperature vulcanized silicone rubber, organic silicone defoamer, advance printing ink, powder coating, PVC resin, unsaturated polyester resin thickening, thixotropic agent, pharmaceutical powder, tabular preparation, cosmetics etc.


S-380Fumed silica S-380 is mainly used for silicone rubber, silicone grease and sealing materials of capacitance  packaging with high transparency and high tear resistance.


SF-215Fumed silica SF-215 is mainly used for organic silicone rubber, organic silicone sealant, paint, coating, printing ink,  toner, copier toner, developer powder, adhesive, battery etc.


SF-615Fumed silica SF-615 is mainly used for printing ink (copier toner), coating, plastic, toothpaste, food, medicine, cosmetics, silicone rubber, sealant, adhesive, gel battery composite material, industrial lubricating oil, unsaturated polyester resin, layered resin and gel coat, insulation glue of cable and cable gel, thickener of synthetic grease, plant protection etc.
