Description
Chemguard 2% High Expansion Foam
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:
Features:
Proportioning:
Foam Properties:
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.
Typical Properties at 77 degrees F (25 degrees C)
Environmental Impact:
Chemguard XTRA High is biodegradable, low in toxicity, and can be treated in sewage plants. Please refer further to Chemguard Technical Bulletin regarding foam products and the environment.
Storage:
If kept in the original unopened and airtight Chemguard supplied container and stored within the temperature range of 35 degrees F - 120 degrees F (2 degrees C - 49 degrees C), a shelf life of between 20 - 25 years can be expected. When stored in other than the original supplied container, check with Chemguard for storage guidelines.
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.
Features:
- 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
Proportioning:
- Fixed or portable in-line eductors
- In-line balanced pressure and pump pressure proportioning skid
- Bladder tank balanced pressure proportioning system
