Silicone Oil (Polydimethylsiloxane, PDMS) is an essential industrial and laboratory fluid known for its low toxicity, non-reactive nature, and exceptional performance. Its low-viscosity grades (10–1000 cSt) provide:
-
Excellent Lubrication for precision instruments, gears, seals, and O-rings
-
Reliable Mold Release in polyurethane, epoxy, and concrete molds
-
Hydrophobic Coating on textiles, paper, and electronic components
-
Defoaming Agent in paints, coatings, and water-based adhesives
-
Wide Thermal Stability (–50 °C to +200 °C) and oxidation resistance
Whether you’re in manufacturing, chemical processing, or product development, Avex International’s Silicone Oil ensures smooth, bubble-free finishes and long-term protection.
