- Technical Details
The thermal silicone fluids are described in chemical notation as aromatic siloxanes because of the presence of phenyl groups. High phenyl content fluids are utilized as heat-exchange fluids, dielectric coolants, impregnants for sintered metal bearing, and base oils for high temperature fluids. Low phenyl content fluids are utilized at lower temperatures than high phenylsilicones and find extended temperature service applications as lubricating oils for critical devices such as timers and systems involving rubber, plastic and aluminum mating surfaces.
