Chemguard XTRA High Expansion Foam Concentrate is a synthetic based foaming agent suitable for use with either low, medium or high expansion foam generating equipment. It is generally proportioned at a 2% concentration (2 parts XTRA to 98 parts of water). When used through a high expansion or medium expansion generating discharge device the following extinguishing mechanism takes place:

  • The large volume of foam engulfs the area being protected and prevents air from reaching the fire.
  • As the foam is generated with water, and comes in contact with the fire, a large amount of steam is generated which helps reduce the oxygen content in the atmosphere.
  • The water content in the foam produces a valuable cooling effect on the fire. This is particularly so with medium expansion generated foam, which has higher water content.


  • Excellent wetting characteristics when used in combating Class “A” fuel type fires
  • If inadvertently frozen, thawing will render the product completely serviceable again
  • Can be used with foam compatible dry chemical agents
  • Suitable with high/medium foam generators


  • Fixed or portable in-line eductors
  • In-line balanced pressure and pump pressure proportioning skid
  • Bladder tank balanced pressure proportioning system


When Chemguard XTRA High is mixed with water in the correct proportion, expansion ratios of up to 1,000 to 1 can be achieved. This expansion ratio is dependent on the type of discharge device and pressure of the system when operating.
