Rheology of Filler Rubber: Silica-Silicone

Abstract

This work focuses on the relationship between the morphology of filled rubber and its behavior at small and large deformations. Composites made from vinyl terminated polydimethylsiloxane and different fumed silicas were prepared. Filler concentration ranged from 0 to 40 phr (part of silica per hundred parts of PDMS). Small deformation tests were done using oscillatory shear and showed coupling of the filler and crosslinking effects as high crosslinking density while the effects are more or less independent at low crosslinking levels. Keywords: Polydimethylsiloxane, Silica filler, Rheology, PDMS, Elastomers and rubber, Silanols, Hydrosilation, Fluid mechanics, Silicone, Reinforcement.
