Hydrophilic Fumed Silica 200 As Anti-Caking Agent

                                     Pyrogenic Silica / White Carbon Black /  Silicon Dioxide

Fumed silica is the superfine micro-nano fine chemical product, which is divided into hydrophilic type and hydrophobic type in accordance with their different surface treatments. Its appearance is white powder. Native particle size ranges from 5nm to 40nm, with significant functions of thixotropy, reinforcing, thickening and filling.It is widely used in the industries of rubber, sealant, plastic, resin, paint, printing ink, papermaking, medicine, cosmetics, food etc.

· 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 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

  Applicaton:                                                              

 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 paints, coatings, printing inks, adhesives and unsaturated polyester resins. It is also used in the production of cat litter box filler.

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

Fumed silica F-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. 

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