In comparison to conventional PDMS silicone oils, DPDM‐400 has much higher thermal stability and remains stable at temperatures > 250°C (open system). When heated, its viscosity lowers very quickly which makes it an excellent choice for high temperature laboratory baths and heat transfer systems that have to circulate and pump the fluid. Conversely, it is not recommended for cold temperature systems due to its acute viscosity increase at lower temps.
As a calibration fluid, DPDM‐400 Silicone Fluid is widely used in Flow Control, Temperature Control and Motion Control technologies. Again, its advantage over conventional oils is that it will not break down at high temperatures and it will not coagulate at high pressures. It is widely used for instruments, gauges, sensors, meters and devices that are subject to extreme temperatures and high pressures.
DPDM‐400 Silicone Fluid has a higher RI value (1.505) than conventional PDMS silicone. It an excellent RI index matching fluid and optical fluid for use in sensor /imaging / LED and Photonics technologies that require a higher RI value than conventional fluids.
