Dimethyl silicone oil, also known as polydimethylsiloxane (PDMS), is a versatile silicone-based fluid widely used across industrial, cosmetic, and personal care applications. It is a linear polymer composed of repeating –[Si(CH₃)₂–O]– units, which gives it exceptional thermal stability, chemical inertness, and flexibility.
This silicone oil maintains a stable viscosity over a wide temperature range, exhibits low surface tension, and provides excellent water repellency and release properties. Its non-corrosive nature, resistance to shearing, and electrical insulation capability make it ideal for applications ranging from lubricants and release agents to cosmetic additives and surface treatments.
Applications:
Lubricants for machinery and plastics
Release agents for molds and coatings
Polishes for automobiles, furniture, metals, and leather
Cosmetic additives and personal care formulations
Antifoam agents in industrial processes
Electrical insulation fluids
