Abstract
Disclosed is modified silica filler material wherein the silica filler material has been surface treated with both an alkyl silane and an alkenyl silane. The modified silica filler material, when included in an elastomeric composition, results in lower compression set and improved mechanical properties including viscosity, tensile strength, modulus and elongation. The filler material can be used at high levels in elastomeric compositions and does not raise the viscosity to unusable levels. The elastomeric composition including the modified filler material finds special use in the formation of gaskets for fuel cells.
