Dimethicone 350

Please note: If you have recently purchased our industrial grade silicone, we have now returned to supplying high grade odourless material.

A high quality of silicone oil which is a clear liquid. Its viscosity shows very little change with temperature variation. It exhibits minimum of change among all types of silicone fluids. Outstanding resistance to high and low temperature extremes, maintenance of flexibility over a wide temperature range are its unique properties.

It shows high resistance to breakdown by mechanical shearing. The low change in viscosity with temperature and excellent heat and cold resistance makes it an ideal lubricant. It is, therefore, widely used in gear wheels, bearings and brushes. It exhibits excellent dielectric properties, which are maintained for prolonged periods of time even under varying operating conditions.

Performance properties:

  • High and low-temperature stability
  • Low pour point
  • Low temperature and pressure dependence of viscosity
  • Good dielectric characteristics
  • Low interfacial energy
  • High surface activity
  • High compressibility
  • Chemical inertness

Uses for Silicone 350:

  • Heat transfer media
  • Thermal transfer fluids
  • Hydraulic fluids
  • Dielectrics fluids
  • Water repellents
  • Polishes
  • Lubricants for eg treadmills
  • Antifoams
  • Mould release agents
  • Oil Baths
