Applications & Uses

Applications
  • Antifriction Agents & Lubricants
  • Heat transfer fluid
  • Pressure transfer fluid
  • Base fluid of lubricants


Application Details : The flash point of the silicone fluid may be changed by heat-stressing. It is therefore particularly important in open systems to check the flash point at least once a year and more often if operating conditions demand.
