Description: Antifoam Silicone Fluids are 100% Polydimethylsiloxane fluids / PDMS Silicone Oils that range in viscosities from 1,000cSt to 1,000,000cSt (centistokes) @ 25°C. In the Oil and Gas industry, PDMS Silicone Fluids are the most effective fluids in reducing process foam in production, refinery and gas processing plants.

PSF Antifoam Silicone Fluids are characterized by their hydrophobic nature, wide service temperature range, high thermal stability, low viscosity change at temperature, high resistance to oxidation, high flash points, low vapor pressure, stability at high pressures, low toxicity and inertness to most materials.

Antifoam Silicone Fluids are insoluble in crude oil but highly soluble in a wide range of conventional solvents such as toluene, xylene, diesel or naphtha. The suggested starting dilution ratio is 20ppm pre-diluted with one of the named solvents and added continually with a meter pump.

Antifoam Silicone Fluids are also used in a wide range of Oil&Gas, military and industrial applications to dampen vibration, dampen pulsation, and dampen torque. The other main application is for use in Flow Control, Temperature Control and Pressure Control Instruments.

High Viscosity Silicone Damping Fluids are particularly effective for use in instruments and gauges that require the highest damping action against vibration, sound and amplitude of motion. By nature, silicone fluids are hydrophobic and prevent humidity from entering the gauge/instrument housing. This is very important. At low temperatures, water condensation can freeze and cause damage to the sensitive parts within the gauge/instrument housing. Ultimately, Silicone Damping Fluids will extend the service life of the equipment that it fills and provide more accurate readings even in the harshest of conditions.

Other applications include : pressure gauges, pressure control instruments, pressure testing equipment, temperature testing equipment, temperature control equipment, pumps, pipeline equipment, flow testing equipment, flow level sensors, electronic sensors, level controllers, rotary dampers, geothermal monitoring equipment, seismology instruments, temperature recorders, temperature measurement equipment, process instruments, process recorders, level sensors, control valves, calibration equipment, flow control instruments, laboratory research instruments, digital display meters, gravity meters, testing equipment, testing instruments, monitoring equipment, pulsation dampeners, level instruments, electro hydraulic actuators, flow meters, thermostats, industrial thermometers, dashpots, aviation instruments, aviation gauges, electronic timer systems, control cables, optical instruments, aviation gyroscopes, process control equipment, test equipment, shock testing equipment, high pressure gauges, subsea gauges, process, gauges, subsea instruments, subsea cables, shock dampeners for R/C vehicles, underwater vehicles, deep sea instruments, deep sea lighting equipment, deep sea cameras, deep sea sensors, deep sea robotics, liquid filled gauges, level controllers, rotary dampers, temperature and process recorders, control valves, calibration equipment, flow meters, thermostats, industrial thermometers, dashpots, monitoring systems, avionic gauges and aviation instruments
