Organo bifunctional silane effects on the vibration, thermal, and mechanical properties of a vinyl-group-containing silicone rubber/natural rubber/silica compound

A bifunctional silane (TESPD) was added to a vinyl‐group‐containing silicone rubber (SR)/natural rubber (NR)/silica compound, and the resulting mechanical, morphological, and thermal properties were compared with those of an NR/silica compound. The addition of TESPD to the silica‐filled SR/NR compou...

Description
Summary:A bifunctional silane (TESPD) was added to a vinyl‐group‐containing silicone rubber (SR)/natural rubber (NR)/silica compound, and the resulting mechanical, morphological, and thermal properties were compared with those of an NR/silica compound. The addition of TESPD to the silica‐filled SR/NR compound formed an SR‐silane‐silica‐silane‐NR structure that behaved as a ter‐polymer. The addition of SR into the NR improved the mechanical properties (torque maximum, modulus, elongation at break, and hardness) and thermal properties as well as the tan δ values. The SR‐silane‐silica‐silane‐NR structure exhibited advanced properties that are suitable for an automotive engine mount application, which requires good thermal and vibration absorption properties.
