Temperature Limits:At or above Atm Pressure: 0 to 315 °C (32 to 600 °F)Viscosity at 25 °C (77 °F): 39 csSpecific Gravity @ 25 °C (77 °F): 1.07Coefficient of Thermal Expansion: 0.00095 cc/cc/C (0.00053 cc/cc/F)Chemical Name: TetramethyltetraphenyltrisiloxaneCAS Number: 3982-82-91.4.1 Description/applicationsSilicone 704 is a fill fluid intended for use in applications with higher operating temperaturesbeyond the maximum limit of Silicone 200.This specialty silicone fluid has a much highermolecular weight than Silicone 200, which increases its operating temperature. Its mainlimitation is its higher viscosity, so heat tracing of capillaries or use of the Rosemount ThermalRanger Expander is suggested for many outdoor applications. The 0.03-in. (0.7 mm) ID capillaryis not allowed for Silicone 704 because of its higher viscosity.For applications below 14.7 psia (1 bar-a) use Silicone 704 for Vacuum Applications found inSection 1.5.
