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
