Aberdeen Foam FRF

Forest and Rural Fire Retardant

A high quality short term forest fire retardant concentrate which provides excellent surfactant properties, accelerating the extinguishment process to improve safety and provide more stable foam.

Designed to quickly extinguish and secure Class A fires including forest and wildfires, Aberdeen Foam FRF is able to provide a barrier between the fire and emergency personnel in order to control and suppress the flames. The complex mix of surfactants, solvents and hydrocarbons creates a low viscosity foam with a low freeze point. The exceptional wetting abilities of Aberdeen Foam FRF means that the foam permeates deep into the source of the fire and secures extinguishment which prevents burn back occurring.

Formulated for use with either fresh or seawater. 

Highly versatile and suitable for use with a range of equipment, methods of application and proportion rates - intended for use between 0.1% and 1.0%.

  • Provides quality protection from Class A fire risks such as rubber tyres, coal, paper & wood and forest fires
  • Economical - proportioning rates of between 0.1% and 1.0%
  • Versatile - can be used in different equipment and application methods
  • Easily premixed and excellent foaming properties

Fire Performance Approvals

Aberdeen Foam FRF has been tested to:

  • Fire Performance (INIA)
  • EN1568:2008 Part 1
  • EN1568:2008 Part 3

Environmental Impact

  • Fluorine free
  • Biodegradable (>90% BOD/COD 28 days)
  • Butyl carbitol free
  • Low toxicity to aquatic organisms
  • No adverse consequence on cultivation


Highly versatile and suitable for use with a range of equipment, methods of application and proportion rates - intended for use between 0.1% and 1.0%.

Aberdeen Foam FRF provides quality protection wherever Class A materials (ie. tyres, paper, wood) present a fire risk.

Suitable of use at Class B minor incidents such as small hydrocarbon liquid spill fires.

Not suitable for use on fuels which are polar solvents and water miscible such as alcohols, ketones, aldehydes and ethers.

Proportioning Information

Aberdeen Foam FRF is intended for use between 0.1 - 1% induction rate:

  • 0.1 - 0.2% use as a wetting agent
  • 0.4 - 0.6% for air attack
  • 1% to create structural foam layer in order to stick to walls, trees, etc.

Designed for use with an electronic proportioner. To ensure accurate proportioning a CAFS system is recommended to be used.

Aberdeen Foam FRF is readily proportioned with the following equipment:

  • In-line inductors (fixed or portable)
  • Balanced pressure variable flow proportioners
  • Around the pump proportioners
  • Bladder tank Balanced Pressure proportioning skid
  • Handline, aspirating nozzles with fixed inductor pickup tube
