PPM-500 Phenylmethyl Fluid is the highest phenyl content silicone fluid. In comparison to conventional PDMS silicone oils, PPM-500 has much higher thermal stability and remains stable at temperatures > 250°C (open system) & 300°C closed 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, PPM-125 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 both extreme temperatures and high pressures.
With its high phenyl content, PPM-500 Silicone Fluid has the highest RI value (1.533). It an excellent RI index matching fluid and optical fluid for use in sensor /imaging / LED and Photonics technologies that require the highest RI value.
