Dow XIAMETER PMX 200

Main features

  • 1,000 cSt Polydimethylsiloxane Fluid
  • Surface Tension of 21.2 dynes/cm
  • Dielectric Strength of 400 volts/mil

Product Description

XIAMETER™ PMX-200 Silicone Fluid 1000 cSt is a colorless, clear polydimethylsiloxane fluid with a nominal kinematic viscosity of 1,000 cSt. The silicone fluid combines low surface tension with water repellency, heat stability, dielectric performance, and resistance to shear breakdown. Its viscosity-temperature characteristics and chemical stability support use as a lubricant and mechanical fluid, while its spreading and release properties make it suitable for mold release, surface treatment, polish formulations, and foam-control applications.

Key features

  • Stable 1,000 cSt silicone fluid: Provides a nominal kinematic viscosity of 1,000 cSt with resistance to shear breakdown and a viscosity-temperature coefficient of 0.61.
  • Low surface tension and water repellency: A typical surface tension of 21.2 dynes/cm at 25°C supports spreading, wetting, release, and water-repellent performance.
  • Electrical and thermal properties: Provides a typical dielectric strength of 400 volts/mil at 25°C and an open-cup flash point above 326°C.

Applications / Suitable for

  • Elastomer and plastics lubrication
  • Mechanical and damping fluids
  • Electrical insulating fluids
  • Mold release and surface-active applications
  • Automotive, furniture, metal, and specialty polish formulations
  • Foam prevention and foam breaking

Electrical Properties
Dielectric Strength
Dielectric strength is measured in kV per mm and is calculated by the Breakdown voltage divided by the thickness of the tested material. Those two properties go hand in hand and while Breakdown voltage is always thickness dependent, dielectric strength is a general material property. As an example, the dielectric strength of Polyimide is 236 kV/mm. If we place 1mm of Polyimide between two electrodes, it will act as an insulator until the voltage between the electrodes reaches 236 kV. At this point it will start acting as a good conductor, causing sparks, potential punctures and current flow.
400 kV/mm
Volume Resistivity
Volume resistivity, also called volume resistance, bulk resistance or bulk resistivity is a thickness dependent measurement of the resistivity of a material perpendicular to the plane of the surface.
