Silico MF2010-500000 cSt Silicone Fluid
Introduction
Silico® MF2010-500,000 cSt Silicone Fluid is an ultra-high viscosity polydimethylsiloxane (PDMS) engineered for industrial applications requiring extreme film thickness, sustained mechanical damping, and long-term operational stability. Part of the Silico® HV-B High Viscosity Series, this grade provides robust lubrication, thermal endurance, and dielectric performance that surpass conventional high-viscosity silicone oils.
With a nominal viscosity of 500,000 cSt at 25 °C, this silicone fluid forms highly cohesive, load-bearing films with minimal flow under shear, making it ideal for heavy-duty mechanical damping, precision motion control, and insulation applications where ordinary fluids lack sufficient body or stability.
