Products Description of Poly(dimethylsiloxane) CAS#9016-00-6
The outward form of Poly (dimethylsiloxane) varies with its molecular‑weight level, covering colourless transparent volatile fluids, high‑viscosity liquids or silicone‑gel substances. This silicone polymer, also known as PDMS, comes with physiological inactivity, stable chemical performance, electric insulating property and outstanding outdoor ageing tolerance.
It supplies extensive viscosity choices, low solidifying temperature, high flash-point value, favourable water-repellent capacity and great anti-shear capability. Long-time service is available between 50-180°C. Besides, PDMS possesses desirable gas permeation capacity, so it ranks as a perfect substrate material for different chemical and biological sensor equipment.
