Technical Information 1246: SIPERNAT® for high temperature vulcanized silicone rubber
(pdf, 356 KB)
In the silicone industry, synthetic silica is used predominantly as reinforcing filler in order to give the silicone rubber sufficient mechanical strength to finally meet its application requirements. In principle both, fumed silica products manufactured according to the AEROSIL®-process and silica grades precipitated in an aqueous suspension, sold by Evonik Industries under the brand name SIPERNAT® specialty silica, are suitable for this purpose.
