Diphyl THT is a high performance heat resistant synthetic HTF
It is a clear, colorless pale yellow liquid. Diphyl THT is odorless and due to its polyphenyl structure (chemically: partially hydrogenated terphenyls), it has a very high thermal stability with a long working life.
Thanks to its high boiling temperature, Diphyl THT can be used in non-pressure systems throughout its working range.
High purity, for example; chlorine and sulfur contaminants ensure that there is no corrosion from metals normally used in heat transfer equipment. The application range is between 0 ° C and 345 ° C. The film temperature should not exceed the 370 ° C limit significantly or take too long.
Application area
Diphyl THT is used worldwide in numerous applications for indirect heating of process plants in the chemical and petrochemical industry. Diphyl THT is primarily used in reactors, polymerization processes, distillation columns and processing machines such as; For the production of synthetic resins, plastic raw materials, polyester films and fibers and for fatty acid processes, phthalic anhydride distillation, polyamide extrusion etc.
In addition, Diphyl THT is used for optimum energy utilization in waste heat recovery in the steel and petrochemical industries.
A good example for the use of Diphyl THT is the production of PBT, PET, purified terephthalic acid (PTA), which is applied in many fiber spinning mills around the world.
