Dow XIAMETER PMX 200
Harmonization Code : 2710199990 |
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
