1. Basic Information
Name: Silicone oil
Alias: Polydimethylsiloxane, Dimethicone
CAS No.: 63148-62-9
Repeating Unit Formula: C2H6OSi1
Molecular Weight: Variable, depends on polymerization degree n
2. Physical and Chemical Properties
Physical Properties
- Appearance: Colorless transparent viscous liquid, different viscosity grades from low viscosity to ultra-high viscosity
- Odor: Odorless
- Solubility: Insoluble in water, methanol, ethanol; miscible with hydrocarbon solvents, halogenated hydrocarbons, ester solvents; incompatible with polar solvents
- Density: 0.960–0.975 g/cm3 (20 °C)
- Refractive Index: 1.400–1.405
- Hygroscopicity: Non-hygroscopic, excellent water repellency
- Surface characteristic: Ultra-low surface tension, good lubrication and demoulding performance
Chemical Properties
- Molecular Structure: Linear polymer with Si-O main chain, each silicon atom bonded to two methyl groups
- Thermal stability: Excellent high temperature resistance, stable at -40 ~ 200 °C; slight decomposition above 250 °C
- Oxidation resistance: Not easy to oxidize under normal temperature; slow oxidation under long-term high temperature and air exposure
- Inertness: Chemically inert, does not react with most acids, alkalis, salts at room temperature
- Compatibility: Compatible with non-polar resins, rubber, mineral oils; incompatible with highly polar materials, anionic/cationic surfactants in high concentration
- Photostability: Excellent UV resistance, no yellowing under long-term light irradiation

Safety Warning
Low-toxicity inert polymer liquid. Liquid splashing into eyes causes mild irritation; long-term skin contact leads to slight skin occlusion. Wear safety goggles during transfer operation. Avoid mixing with strong oxidants at high temperature. Waste silicone oil belongs to recyclable industrial organic waste, centralized recovery treatment is recommended.
