Reolosil

Reolosil is generally supplied in multi-layer paper bags. Standard grade (bulk density: approximately 50g/L) and compact grade (approximately 100g/L) REOLOSIL bags are 10 kg and 15 kg, respectively.

Reolosil is manufactured by controlled combustion of highly purified chlorosilanes with oxygen and hydrogen. A schematic diagram is given below. The silica generated in the flame is transported to HCI removal process, cooling process, adjusting the bulk density process and packaging process in the closed-system.

Reolosil has numerous applications due to its remarkable properties, including high purity, excellent 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, adhesives and materials used to improve flow characteristics.

• High Purity: Highly purified chlorosilanes are used as the raw materials of Reolosil. Rigorous production process controls safeguard against product contamination.
• Excellent Dispersion: In the flame of the reactor, the first produced non-microporous primary particles fuse into aggregates that form larger agglomerates upon cooling. In liquid systems, Reolosil is finely dispersed and exhibits thickening and thixotropic effects, as three-dimensional networks of Reolosil particles form under optimum dispersion conditions.
• Adding Reolosil improves the mechanical properties of elastomers. Especially using the large specific surface area of the Reolosil into the elastomers, the transparency property of the products is also excellent because the dispersion proceed to the aggregates smaller than light wave length (400~760nm).
• Enormous Surface Area: Fumed silica consists of extremely fine particles with large specific surface areas on the order of 50-500 m /g and particles averaging 5-50 nm in diameter. Primary particles do not exist in isolation; they form aggregates and agglomerates.
• Surface Chemistry: Silanol groups (about 1.5 silanol groups per nm? ) are found on the surface of hydrophilic Reolosil grades. In storage, untreated REOLOSIL is hygroscopic. Hydrophobic Reolosil is manufactured by allowing the surface silanol groups of hydrophilic Reolosil to react with various surface-treated agents. This treatment reduces the number of silanol groups to less than 10% of hydrophilic Reolosil. Hydrophobic Reolosil is characterized by low water adsorption for more effective rheology control in complex solvents and easier dispersion in nopolar media.
