  • Heat cured rubbers
    Patent number: 5623028
    Abstract: Control of the surface silanol density in silica fillers used in formulating heat curable rubbers enables control of the percent sealing force retention of the composite. Functionalizing the chemical agents used to effect such control adds additional means of controlling the physical properties of the resulting rubbers, especially silicone rubbers.

  • Method for making fumed silica having a reduced aggregate size and product
    Patent number: 5340560
    Abstract: A method is provided for making fumed silica aggregate having an average convex perimeter in the range of about 0.12 micron to about 0.6 micron based on the combustion of a mixture of a silicon compound, such as an organosilane, an oxygen containing gas, such as air and a fuel such as hydrogen. The fumed silica aggregate has been found to enhance properties in heat curable filled silicone compositions.
