LASTS LONGER
Duratherm S is a high performance, extremely stable, long lasting silicone based heat transfer fluid. Virtually unaffected by oxidation under 204ºC (400ºF), Duratherm S is perfect for use in a variety of applications requiring a safe, non-reportable, non-toxic and non-corrosive heat transfer fluid.
- Features
- Highest Duratherm flash point
- Silicone-based fluid
- Great oxidation stability for open baths
- Non-toxic/non-hazardous
- Includes free fluid analysis and tech support
Applications & Uses
- Markets
- Applications
Duratherm S is ideal for applications such as negative pressure mold heaters, annealing tanks, open bath forming, or any processing equipment where oxidation is prevalent and problematic. Duratherm S resists the affects of oxidation seen with most other heat transfer fluids.
High temperature stability is maintained to 315ºC (600°F), this combined with a low end working temperature of -51°C (-60°F) also makes Duratherm S ideally suited for low temperature applications, batch processing application requiring a single fluid for both heating and cooling.
