Synthetic fiber manufacturing

Heat transfer fluids have been used in the manufacturing of synthetic fibers for over 50 years. Nylon 6, nylon 6,6, PET, and various other polyesters and textiles require high-temperature processes for production. Each step of the process, whether it be polymer manufacturing, spinning, heat treating, annealing, or drawing, can use heat transfer fluids. Both liquid-phase heat transfer fluids and vapor-phase heat transfer fluids can be used, depending on the type of operation being performed. The correct physical properties, heat transfer efficiency, and high thermal stability are the key characteristics needed from heat transfer fluids for these demanding applications. Eastman Therminol® heat transfer fluids are the most widely used around the world in this industry.

Therminol VP-3 Temperature Graphic

Therminol VP-3 heat transfer fluid is a synthetic heat transfer fluid that was specially developed to allow vapor-phase heat transfer at lower temperatures than are practical with traditional diphenyl oxide (DPO)/biphenyl constituted fluids like Therminol VP-1.

Therminol 66 Temperature Graphic

Therminol 66 is the world’s most popular high temperature, liquid-phase heat transfer fluid. Therminol 66 is pumpable at low temperatures and offers high-temperature thermal stability.

Therminol VP-1 Temperature Graphic

Therminol VP-1 heat transfer fluid is an ultrahigh-temperature synthetic heat transfer fluid designed to meet the demanding requirements of vapor-phase systems or liquid-phase systems.
