Dimethyl silicone fluids

Fig. 4. Kinematic viscosity—temperature relationship of dimethyl silicone fluids.

Certain cerium and iron compounds, when properly incorporated by preoxidation, are excellent antioxidants for dimethyl silicone fluids (DMS) and methylphenylsilicone fluids (MPS). The useful life of these stabilized fluids depends on the temperature, on the concentration and dispersion of the redox metal moieties, and on the conditions of aeration—better aeration providing the longer useful life with inhibited DMS. A mechanism of stabilization by the redox metals has been proposed to account for the observed data. [Pg.110]

Silicone Rubbers. As pointed out earlier, the silicone rubbers are formed by reaction of a peroxide with a dimethyl silicone fluid. In practice, the fluid, peroxide, and appropriate inorganic iillers (titanium diojdde, ranc oxide, iron oxide, silica, etc.) are milled together. Molding at about 150 C develops the rubbery product. By alteration of the polymer and by appropriate selection of kind and amount of filler, rubbers of different types may be prepared. [Pg.979]
