Key Players
Competitive Landscape
Competition begins with the circuit’s operating limits. Glycol-based fluids address freeze protection and moderate-temperature service, while thermal oils and other specialty chemistries cover different heating duties. Suppliers also compete on the ability to interpret samples, plan a cleanout and replenish a compatible grade. These services matter when a processor must keep an installed system running through several maintenance cycles.
Dow’s March 2024 alternative-feedstock launch and Fuchs Lubricants’ July 2024 LUBCON acquisition address different purchasing needs: raw-material sourcing and specialty-fluid supply. Product-level eligibility remains a separate consideration, illustrated by the NSF records for CASSIDA FM HEAT TRANSFER FLUID 32 and Therminol D-12.
Company developments mapped to drivers, trends and opportunities (2026-2036)
| Development | Driver | Trend | Opportunity |
|---|---|---|---|
| March 2025: NSF’s certificate for CASSIDA FM HEAT TRANSFER FLUID 32 lists HT1 registration and ISO 21469 certification. | Food plants evaluate incidental-contact suitability alongside hygiene requirements when selecting a thermal fluid. | Product registration and lubricant hygiene certification address different aspects of the qualification file. | A combined documentation package can simplify the technical review of a suitable fluid. |
| February 2026: NSF’s certificate lists Therminol D-12 under HT1 registration number 130383. | Plants need a synthetic heating or cooling fluid with a current third-party eligibility record for closed-loop indirect-heating circuits. | Synthetic fluids offer an alternative to glycol formulations for suitable operating temperatures. | Formulators can capture indirect-heating replacement work by extending HT1 registration across additional synthetic fluid grades. |
| March 2024: Dow launched bio-circular and circular propylene glycol offerings in North America using mass-balance accounting for alternative feedstocks. | Formulators need a lower-carbon feedstock route that still preserves food-grade purity and inhibitor performance. | Lower-carbon chemistry is becoming part of capital-project and energy-audit discussions instead of a separate sustainability initiative. | Suppliers can pair lower-carbon propylene glycol with heat-recovery project support for customers pursuing efficiency and emissions goals together. |
Clariant, Paratherm, Global Heat Transfer, Radco Industries, Dynalene and Duratherm offer further thermal-fluid options. Chemours supplies refrigerants used in related cold-chain systems.

The choice between these suppliers depends on the circuit’s temperature range, fluid chemistry and maintenance needs.
Who leads the food grade heat transfer fluids market?
Eastman, Dow and Clariant offer established chemical platforms for multiple markets. Paratherm, Global Heat Transfer, Radco Industries, Dynalene and Duratherm specialize in thermal-fluid selection and service. Their competitive strengths differ between cooling loops and higher-temperature heating systems.
Which companies have documented qualification or quality approvals?
Fuchs Lubricants publishes current NSF HT1 registration and ISO 21469 certification for its CASSIDA FM HEAT TRANSFER FLUID 32 product. Eastman holds current NSF HT1 registration under number 130383 for Therminol D-12. The two records provide independent qualification evidence for fluids used in incidental food-contact settings.
Which companies provide synthetic or specialty thermal-fluid chemistries?
Paratherm, Global Heat Transfer, Radco Industries, Dynalene, and Duratherm supply specialty thermal-fluid portfolios and technical selection support for repeat ordering. Eastman and Dow serve synthetic and glycol-based chemistries that combine documented fluid platforms with broader chemical-manufacturing requirements.
Which companies serve North America and Europe?
Eastman and Clariant document active fluid distribution in both North America and Europe. Fuchs Lubricants also operates lubrication and specialty-fluid routes in both regions, while Paratherm and Dynalene retain a stronger North American commercial emphasis.
