- Application Details
- For practical purposes, the useful temperature range of WACKER® AP 500 is between -35 °C and +200 °C.
- However, this presupposes that heat-stressing of the fluid occurs under "chemically pure" conditions.
- Even trace amounts of acids, alkalis, mineral oils, organometallic compounds, metal salts or metal oxides can seriously reduce the service life.
- 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.
