Silicone fluids<br />
Silicones generally increase in viscosity with increasing chain length. In silicone<br />
fluids, the number of dimethylsiloxane moieties (indicated by the "n" in<br />
the chemical formulae) is up to 4000 (Ullmann 2003).<br />
Silicone fluids are distinguished from common organic fluids by a number of<br />
unique properties (Ullmann 2003):<br />
• Good thermal stability (150-200°C);<br />
• Good low-temperature performance (
