Physical Properties As the viscosity of the Halocarbon oils increase, so does the density, pour point and cloud point. Table 3 (p. 7) lists these and other physical properties. The vapor pressure is inversely related to viscosity of the oil, as shown in Figure 1 (p. 9). The viscosity of an oil decreases with temperature as shown in Figure 2 (p. 10). These data will help choose the appropriate oil for a particular application. The polymers change from oils to waxes as the viscosity increases. The waxes are all white solids at room temperature that melt upon heating. They have initial boiling points above 260°C (500°F) and densities of about 1.89 g/mL at 99°C (210°F). Drop melting point and viscosity data are given in Table 4 (p. 7). The properties of Halocarbon greases depend upon how heavily they are gelled. Table 5 (p. 8) gives penetration, service temperature range and drop melting point data. Solubility of Halocarbon Fluids in Other Solvents The lower viscosity Halocarbon oils are soluble in most organic liquids but solubility decreases as viscosity increases. All Halocarbon fluids are insoluble in aqueous solutions however stable emulsions are possible with fluorinated surfactants. Solubility of Other Substances in Halocarbon Fluids Halocarbon fluids will dissolve halogens and volatile anhydrous inorganic salts (such as titanium tetrachloride). Typical organic materials with which various Halocarbon oils are miscible are: Acetone Amyl acetate Benzene n-Butyl alcohol Carbon disulfide Dioctyl phthalate Dioctyl sebacate Ethanol Ether Glacial acetic acid Hexane Isopropyl alcohol Kerosene Methanol Methyl ethyl ketone Methyl isobutyl ketone Methylene chloride Mineral oils Silicone oils Tetrachloroethylene Trichloroethylene back to Contents 6
