F-500 Encapsulator Agent (F-500 EA)

The answer to today’s growing fire hazards in commercial buildings, residential settings, industrial facilities, power plants, aviation, and more.

Hazard Control Technologies' F-500 EA.

Materials like flammable metals, lithium-ion batteries, and synthetic fabrics have become commonplace in the home, at work, and in industrial facilities, challenging traditional fire suppression and detection systems. F-500 Encapsulator Agent, a premier fire suppression agent, offers unparalleled features that give your team the ability to safely mitigate these difficult-to-extinguish fire hazards.

F-500 Encapsulator Agent is not a foam. While a traditional foam system works on a mechanical level, Encapsulator Agents work on a chemical molecular level, changing the composition of plain water. There are different types of systems for suppressing different types of fires, but the F-500 EA ensures a comprehensive approach to target the affected area efficiently and correctly.

For those concerned about environmental compliance, it’s important to note that Encapsulator Agents do not contain any fluorinated active ingredients reportable under the Superfund Amendments, Re-authorization Act (SARA) Title III, Section 313, or Comprehensive Environmental Response Compensation Liability Act (CERCLA). The shelf life of the F-500 Encapsulator Agent is 15 years. It can be discarded as a non-hazardous waste under RCRA CFR261.

NFPA 18A Section 7.7

Spherical Micelle Stability Testing

“This section covers the test procedures to evaluate the ability of a water additive solution to form and maintain stable spherical micelles capable of encapsulating combustible and flammable liquids (polar and non-polar), rendering the flammable liquids nonflammable, nonignitable and nonexplosive and maintaining that encapsulation in the presence of high heat over an extended period of time.”

NFPA 18A Annex 4.3

Lithium-ion Battery Testing

“Encapsulator Agents (Sec. 7.7) have been tested extensively by third-party testing organizations. This testing has been controlled, scientific and highly instrumented, documenting fire suppression, control and elimination of thermal runaway and encapsulation of both flammable electrolyte and other explosive off-gases, rendering them nonexplosive. Encapsulator Technology reduces the toxicity of HF gas.”

Encapsulator Agents

Beyond traditional fire sprinkler systems, Encapsulator Agents bring several unique features to the table. Beginning as a singular molecule with a polar head and non-polar tail, the addition of F-500 EA concentrate is designed to enhance efficiency and expand your fire suppression capabilities. F-500 EA is compatible with leading sprinkler head systems and deluge systems.

Fire Chemistry

Our F-500 Encapsulator Agent suppression system works on all four legs of the fire tetrahedron simultaneously.


Unlike fire protection systems that rely on traditional fire suppression methods, Encapsulator Agents excel at encapsulation, separating the fuel from oxygen on a molecular level.


A heat source is required for ignition to occur. Through the process of rapid heat reduction, thermal energy is absorbed up to 10x faster than plain water, preventing the spread of fire.


F-500 encapsulation separates the oxygen from the fuel source. Oxygen is needed to support the combustion reaction, so when it’s removed, that reaction is interrupted.

Chemical Reaction

During the process of extinguishment, F-500 EA absorbs free radical energy, halting the chemical chain reaction that sustains flames. This process is called free radical interruption.

Unique Features

When it comes to a fire suppression system, these unique features make Encapsulator Agents the most versatile agents available today, standing out from typical foam systems or dry chemical solutions:


Encapsulator Agents encapsulate polar and non-polar fuels on a chemical molecular level. NFPA 18A Section 7.7


  1. Expand Hazard Mitigation Capabilities
  2. Establish Confident Incident Response
  3. Establish Long-term + Stable Burn Back Resistance
  4. Prevent Re-ignition

Rapid Heat Reduction

Encapsulator Agents create a thermal circuit, forming an outer layer of agent “skin” on each droplet that drives heat into the internal portion of the droplet.


  1. Expand Rapid Knockdown Capabilities
  2. Improve Droplet Utilization
  3. Prevent Scalding Steam + Excess Runoff
  4. Decrease Time, Resources + Exposure

Free Radical Interruption

Encapsulator Agents absorb free radical energy, interrupting the free radical chain reaction.


  1. Reduce Carcinogenic Toxin Concentration
  2. Improve Health + Longevity
  3. Improve Visibility + Air Quality
  4. Reduce Environment Contamination


Encapsulator Agents are fluorine free, biodegradable and non-corrosive. Their active ingredients contain no PFOA/PFAS.


  1. Improve Community Health
  2. Prevent Hazardous + Costly Cleanup
  3. Prevent Environment Contamination
  4. Prevent Machinery Deterioration


Fire Hazards

Encapsulator Agents are the perfect solution for a wide variety of fire hazards, including three-dimensional fires and energized environments. that require a specialized fire suppression approach. F-500 Encapsulator Agent is recommended for Class A, Class B (Polar + Non-polar), Class D, and Lithium-ion Battery fire hazards, ensuring that business owners and fire service professionals have a reliable fire suppressant on their fire trucks and in their fire protection systems

Below is a comprehensive chart comparing each fire hazard class with the percentage of F-500 EA needed to successfully extinguish the fire.
