Patent number: 5677411Abstract: Secondary contact adhesion or self-bonding in cured liquid injection molding silicone compositions is reduced by the inclusion in the composition of an inhibitor compound selected from the group consisting of phenyl fluids, titanate esters, and silicate esters.Type: GrantFiled: August 28, 1996Date of Patent: October 14, 1997Assignee: General Electric CompanyInventors: Brian J. Ward, Robert A. Smith, Richard A. Striker
-
Patent number: 5573189Abstract: An extrudable composition formed of a blend of a polymer and a finely divided filler is prepared by combining the materials under conditions of high shear forces resulting in a composition which when diluted to a selected level has an application rate which is relatively higher than a composition having the same relative proportions of polymer and filler combined under conditions of low shear, the high shear forces reducing the aggregate size. The invention is also directed to a method for reducing the initial average aggregate size of a filler dispersed in a polymer by subjecting the mixture to high shear forces in a high intensity mixer.Type: GrantFiled: July 24, 1995Date of Patent: November 12, 1996Assignee: General Electric CompanyInventors: Brian J. Ward, Edward M. Jeram, Richard A. Striker, Lawrence M. Wichelns

Patent number: 4011929Abstract: There is provided a new improved dampening medium for a shock dampening device. The dampening device comprises a closed chamber, a movable piston rod extending through the chamber and an enlarged piston head located on the piston rod. Located in the interior space of the closed chamber under pressure is a compressible solid, fragmented, particulate mass of cured unfilled silicone rubber composition for producing a damping effect on the piston rod and head. The damper device includes a threaded plug for varying the internal static pressure on the compressible mass within the chamber and apertures extending through the piston head or an annular space between the outer edge of the piston head and the interior of the chamber for bypassing the compressible mass.Type: GrantFiled: May 2, 1975Date of Patent: March 15, 1977Assignee: General Electric CompanyInventors: Edward M. Jeram, Richard A. Striker

Patent number: 3957713Abstract: There is provided an organopolysiloxane composition combining high strength with exceptionally good elongation, which composition comprises a first component, a mixture of two vinyl-containing polysiloxanes or blends of vinyl-containing polysiloxanes, one of which is a high viscosity polysiloxane or a blend of high viscosity polysiloxanes, the other is a low viscosity polysiloxane or a blend of low viscosity vinyl-containing polysiloxanes, a filler and an effective amount of a platinum catalyst.The second component comprises a hydrogen-containing silane or polysiloxane. When it is desired to cure the composition into an elastomer the first component is mixed with the second component, that is, the hydrogen containing silane or polysiloxane and the mixture is allowed to cure either at room temperature or at elevated temperatures. Part of the total high viscosity vinyl-containing polymer can be mixed with the second component.Type: GrantFiled: August 12, 1974Date of Patent: May 18, 1976Assignee: General Electric CompanyInventors: Edward M. Jeram, Richard A. Striker
