  • Compounding filled silicone compositions
    Patent number: 6391234
    Abstract: High levels of inorganic filler, processing fluid and silicone polymer are compounded and devolatilized into homogeneous filled compositions with requisite reinforcing properties and levels of volatiles. In the method, a filler, processing fluid and silicone polymer are mixed in a first compounding apparatus to produce a dispersed composition containing volatiles. The dispersed composition is then compounded in a long extruder having an L/D ratio of greater than 50 to devolatilize the dispersed composition.

  • Method of steam stripping an inorganic powder
    Patent number: 6030660
    Abstract: The invention provides a method of steam stripping an inorganic powder by contacting the inorganic powder with a silylating agent to form a silylated mixture which is pneumatically transported and contacted with steam to form a vaporous stream. This vaporous stream is then transported to a separation stage and the volatile materials are separated from the inorganic powder.

  • Method for rendering inorganic powder hydrophobic
    Patent number: 5652017
    Abstract: Inorganic powder, preferably fumed silica, is rendered hydrophobic by treatment with a silylating agent in the presence of a third reagent selected from the group consisting of protonic acids, especially those having a boiling point at atmospheric pressure up to 120.degree. C., preferably formic acid, and linear phosphonitrilic halides, preferably linear phosphonitrilic chlorides.
