Name: DOW XIAMETER PMX-200 Silicone Fluid 500000 cSt
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of DOW XIAMETER PMX-200 Silicone Fluid 500000 cSt

Extremely high viscosity (500,000 cSt at 25 °C) provides exceptional film strength and lubricity under heavy-load conditions.
Outstanding thermal stability — maintains performance across a wide temperature range from –40 °C to +200 °C.
Chemically inert and hydrophobic, offering excellent resistance to water, oxidation, and UV exposure.
Low volatility and negligible vapor pressure ensure minimal evaporation loss during long-term service.
Compatible with common elastomers and metals, reducing risk of swelling, corrosion, or degradation in sealed systems.

Typical Applications Of DOW XIAMETER PMX-200 Silicone Fluid 500000 cSt

High-performance lubricants for precision gears, rotary seals, and slow-moving mechanical joints in industrial equipment.
Base fluid in specialty greases for aerospace actuators and automotive brake systems requiring extreme-temperature reliability.
Damping and shock-absorbing fluids in vibration isolators and precision instrumentation.
Dielectric fluid in high-voltage capacitors and transformers where thermal and electrical stability are critical.
Release agent carrier and surface treatment medium for silicone rubber molding and composite tooling.
