100% Active Polydimethylsiloxane (PDMS) — Industrial, Food Grade & Specialty Applications

XIAMETER™ PMX-200 Silicone Fluid by Dow is a 100% active polydimethylsiloxane (PDMS) polymer — tasteless, odourless, and non-toxic. It delivers outstanding thermal stability across –50°C to +250°C, excellent electrical insulation, and inherent water repellency.

PMX-200 is insoluble in water, highly soluble in organic solvents, and easily emulsified with standard techniques. It exhibits high compressibility, high shearability without breakdown, low surface energy, and very low vapour pressure — making it ideal for a wide range of industrial, pharmaceutical, cosmetic and specialty applications.

Available in viscosities from 0.65 cSt to 60,000 cSt. Industrial and food-grade stocked in the UAE. NSF-compliant food-grade available at 1,000 cSt.

Key Performance Features

Extreme Temperature Stability

Operates reliably from –50°C to +250°C — maintaining viscosity and performance where petroleum oils fail, degrade or oxidise.

Non-Toxic & Inert

Tasteless, odourless and non-toxic. Essentially inert — compatible with metals, plastics, rubber and most process media without reaction or degradation.

Outstanding Dielectric Properties

High dielectric strength and low dielectric constant make PMX-200 ideal for transformer fluids, electrical insulation and electronic component applications.

Inherent Water Repellency

Naturally hydrophobic — water beads on treated surfaces. Ideal for waterproofing, surface protection, release agents and anti-adhesion coatings.

Wide Viscosity Range Available

Available from 0.65 cSt to 60,000 cSt — enabling precise selection for damping, lubrication, heat transfer, polishes and specialty formulations.

Low Surface Tension

Very low surface tension enables excellent spreading and wetting — ideal for anti-foam applications, release agents, polishes and surface treatment formulations.

Typical Applications

Heat transfer fluids

Mould release agents

Electrical insulation fluids

Damping & dashpot fluids

Anti-foam base fluids

Diffusion pump oils

Pharmaceutical processing

Textile softening

Cosmetics & personal care

Polish & surface treatment

Hydraulic fluids

Waterproofing agents
