Silicone oil is a synthetic, liquid polymer made of alternating silicon and oxygen atoms (siloxanes) with organic side chains, most commonly methyl groups. Formally known as polydimethylsiloxane (PDMS), it is prized across industries for its incredible stability under extreme conditions. Unlike mineral or vegetable oils, it remains completely stable at both very high and very low temperatures without breaking down or gumming up. [1, 2, 3, 4, 5]
Core Properties
Thermal Stability: Operates seamlessly across temperatures ranging from -50°C to 250°C.
Chemical Inertness: Highly resistant to oxygen, UV rays, moisture, and chemical corrosion.
High Dielectric Strength: Acts as an exceptional electrical insulator.
Low Surface Tension: Spreads incredibly evenly over minute gaps and surfaces.
