Elastomeric composites. I. Silicone composites

Abstract The reinforcement of poly(dimethylsiloxane) (silicone rubber) imparted by different types of fillers was investigated. Three different techniques of incorporation of silica were compared: the usual blending process, in situ filling process, and introduction of spherical colloidal silicas (Stöber silicas). In addition, results obtained with other types of fillers—layered silicates and fibrous clays—were discussed. The role of filler is assessed essentially through the mechanical properties of the silicone composites. © 2004 Wiley Periodicals, Inc. J Appl Polym Sci 93: 2095–2104, 2004
