Poly(dimethylsiloxane）CAS#9016-00-6
Chemical Stability and Inertness: PDMS is physiologically inert and chemically stable, making it ideal for use in medical and industrial applications without reacting with other materials.
Wide Temperature Range: It can operate effectively over a broad temperature range from -50°C to 180°C, ensuring reliability in diverse environments.
Excellent Hydrophobicity: PDMS demonstrates outstanding water-repellent properties, making it ideal for use in applications requiring moisture resistance.
Electrical Insulation and Shear Stability: With its superior electrical insulation and resistance to shear stress, PDMS is widely used in electronics and other high-stability applications.
Depending on its relative molecular mass, polydimethylsiloxane (PDMS) can appear as a colorless, transparent, volatile liquid, a highly viscous fluid, or even a silicone gel. It exhibits remarkable physiological inertness and chemical stability, along with excellent electrical insulation and strong resistance to environmental factors.
PDMS possesses a broad viscosity range, low freezing point, high flash point, and outstanding hydrophobicity and shear stability. It can operate effectively over extended periods at temperatures from -50°C to 180°C. Additionally, PDMS demonstrates superior permeability, making it an ideal carrier or matrix material for a variety of biochemical and biosensing applications.
