Dowtherm synthetic heat transfer fluids have been used in the manufacturing of synthetic fibres like Nylon 6, Nylon 6,6, Poly Oriented Yarn and Polyester Staple Fibre for over 50 years. These fluids have been used both in the liquid and vapour phases in each step of the manufacturing process like polymer manufacturing, spinning, annealing, heat treating and drawing.
Dow is one of the leading suppliers of heat transfer fluids to synthetic fibre manufacturers around the world.
Dowtherm A is a eutectic mixture of Diphenyl Oxide and Biphenyl, which is the most widely used heat transfer fluid in the world. This product can be used in the liquid or vapour phases between 15°C and 400°C and has an atmospheric boiling point of 257°C.
Dowtherm RP is a liquid phase heat transfer fluid with an operating range of -20°C to 350°C. This product minimizes the risk of fouling, scaling and coking by preventing the formation of high boilers upon thermal degradation.
Dowtherm T is a liquid phase heat transfer fluid for moderately high operating temperatures from -10°C to 288°C. It can be used to an extended bulk temperature of 305°C. This product is an economical synthetic replacement for mineral oils to improve efficiency and service life for moderate temperature requirements.
