- For practical purposes, the useful temperature range of WACKER® AP 1000 STAB is between -35 °C and +250 °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.
