The predicted optimum formulas (tables 7 and 8) indicate that a slightly higher loading of the BXS-245 precipitated silica, but at a significantly lower loading of process aid, is required to match the reinforcement obtained using fumed silica.
The dispersion of BXS-245 precipitated silica is essentially equivalent to fumed silica which provides additional evidence that BXS-245 gives reinforcement equivalent to fumed silica in silicone rubber.
Hence, with the increasing production of silicone rubber, the demand for fumed silica is also rising.
With the increasing use of liquid silicone rubber in wearables and medical devices, manufacturers in the fumed silica market are focusing on designing high-structure and high-surface-area fumed silicone especially for liquid silicone rubber.
In addition to the fumed silica AEROSIL[R] and the precipitated silica ULTRASIL[R], SIPERNAT[R], ZEODENT[R] and SPHERILEX[R], Evonik also produces silica based matting agents under the brand name ACEMATT[R]
and other fumed metal oxides under the brand AEROXIDE[R].
[ClickPress, Thu Nov 22 2018] In order to study the various trends and patterns prevailing in the concerned market, Fact.MR has included a new report titled "Fumed Silica Market: Future Forecast Indicates Impressive Growth Rate through 2028" to its wide online database including upcoming trends and growth factors.
The country accounts for almost one third of the total volume sold in Western Europe and is particularly strong in its use of precipitated silicas and silicates, fumed silica, silica gel and high-purity quartz.
