Fumed Silica
Product overview Application Product classification
 Generic names  Fumed Silica
 Product name  REOLOSIL
 Packing / shipping method  Flexible containers, paper bags
 Chemical formula  SiO2
Product overview

REOLOSIL is fumed silica manufactured under strict production controls using highly purified raw materials. The product is a powder composed of primary particles between 5 to 50 nanometers in size.
Main Applications

The use of REOLOSIL as a reinforcing and bulking agent in elastomers such as silicon rubber contributes to greater strength and stretching properties.
Sealants (*1)
The viscosity of a solvent can be adjusted by addition of REOLOSIL, giving it thixotropic properties (*2) (improvement in workability). In addition, other properties of elastomer strengths can also be increased through the use of REOLOSIL.
*1 Rubber-like materials used in the gaps between the frames and glass of windows to adhere and seal both sides.
*2 This refers to the property in which a material in an undisturbed static state resists flowing, but flows freely when force is increased.
Liquid resins
REOLOSIL is used for its anti-sagging properties and also to prevent the settling of pigments contained in paints, adhesives and other liquids.
Added to various powders, REOLOSIL improves the flowability of the powder and prevents the powder from caking.

・ Efficiency of tribo-electric charge
・ Controlling the electric charge
・ Toner transfer to the paper
Special characteristics
REOLOSIL is microparticles manufactured by gas phase reaction, and forms loose agglomerates. By dispersing it moderately, it can be dispersed in particles smaller than the wavelength range of visible light.
REOLOSIL is available in various hydrophilic grades and hydrophobic grades produced from hydrophilic silica through hydrophobic.
