FLUORINATED COMPONENTS FOR AFFF, AR-AFFF, FFFP, AND AR-FFFP FORMULATION

For the formulation of fluorinated foam concentrates, we offer the most comprehensive line worldwide of products equivalent to those of Chemguard, Chemours, and Dynax. Our products are chemically equivalent to those they are intended to replace and can therefore be used in the formulator’s concentrate without the need for recertification.

For experienced formulators with fire-testing capabilities, we also offer two specialty fluorosurfactants, an anionic (HT1030), and a cationic (HT1060). As this is advanced product development work, it’s best suited for experienced groups.

FIRE-EX HT3200 AVIATION GRADE FLUORINE-FREE FOAM CONCENTRATE

Concerns about the accumulation of PFAS in residential areas and aquatic environments have triggered a move to synthetic fluorine-free foams (SFFFs). These foams perform inferior to fluorinated foams, so their environmental benefits should be carefully weighed against the potential for devastating fires. SFFFs that meet ICAO, UL and EN standards are available from some foam companies. Most of them, however, contain polysaccharides and exhibit very high viscosity, which makes them unsuitable for Air Rescue Fire Fighting vehicles, especially in cold climates.

In 2023, the US Department of Defense established MIL-PRF-32725 for foam concentrates used in municipal airports. The specification requires:

  • Excellent performance on Jet A fuel and ethanol-free gasoline
  • Newtonian (low viscosity at 5°C)
  • Low corrosion
  • Low environmental toxicity
  • Good biodegradability (BOD/COD)

It also contains strict requirements for PFAS, degradation on storage, and aquatic toxicity. The R&D efforts of HT&K Anti-Fire resulted in FIRE-EX HT3200. It exceeds all performance requirements set forth in MIL-PRF-32725*.

FIRE-EX HT2070 CONCENTRATE FOR LITHIUM-ION BATTERY FIRES (FLUORINE-FREE)

The proliferation of lithium-ion battery powered devices has presented the world with a rapidly increasing problem: Catastrophic lithium-ion battery fires. The high energy density of these

batteries poses an inherent risk of a thermal runaway. Once initiated, thermal runaway can lead to catastrophic fires and explosions, and release of toxic gases.

This escalating problem led to more than 4,000 battery fires annually. Lithium-ion battery fires have been the main cause of fatal fires worldwide, surpassing blazes caused by cooking and smoking.

Traditional foams operate by starving the fire of oxygen, but lithium-ion battery fires require no atmospheric oxygen for combustion. That is why traditional foams cannot extinguish lithium-ion battery fires.

At HT&K we have developed FIRE-EX HT2070, a fluorine-free concentrate. It can be used at 1.5-3.0% proportioning rate to combat battery fires. Its operating principle is rapid spreading onto the battery pack, cooling the surface and inhibiting thermal runaway.

A study using FIRE-EX HT2070 on 280Ah lithium-ion battery fires was conducted at the China University of Science and Technology. The following results were recorded:

· Extinguishment times reduced by 65% to 81%

· Secondary thermal runaway time extended form 6.5 min. to 16.25 min.

· Surface cooling effect keeping the battery surface temperature below 100°C

· Emission of taxic gases at very low levels

FIRE-EX HT2070 is currently tested by EV and e-bike manufacturers. It is suitable for sprinklers and fire extinguishers.
