SUNOIT industrial dimethyl silicone oils span a viscosity range from 5 to 60,000 cSt. These polydimethylsiloxane fluids are colorless, odorless, and chemically inert. Low-viscosity grades offer excellent spreadability for precision lubrication and defoamer actives; medium viscosities serve as release agent base fluids and water-repellent treatments; high viscosities deliver long-lasting lubrication and damping. Widely used in machinery, textiles, rubber and plastics, building protection, etc. With consistent high purity and flexible supply, SUNOIT provides reliable, full-range silicone base fluids to support diverse industrial formulations.
