Pdms, silicone oil, dimethyl silicone fluid, dimethicone, simethicone, polydimethyl siloxane fluid, dimethylpolysiloxane Jh-201 standard viscosity pure silicone fluids are clear, colorless, and odorless linear polydimethylsiloxane (cas no. 63148-62-9) fluids that range in viscosities from 50cst, 100cst, 200cst, 350cst (food grade), 500cst & 1, 000cst. Pure silicone fluids are characterized by their, excellent lubrication, high dielectric strength, high damping action, high resistanc to shear, thermail stability and wide service temperature range (-50â°c to 170â°c open system) (-50â°c to 250â°c closed system). Polydimethylsiloxanes fluids are used in a wide range of applications that include damping fluids, o-ring lubricants, heat transfer fluids, high and low temperature bath fluids, dielectric applications, water-repellency applications and high shear applications. Pure silicone fluids meet federal specification vv-d-1078 "silicone as damping fluid". They are used in a wide range of military, industrial and avionic gauges, meters, instruments, and monitoring systems.
