Additives are used in fighting fires because some classes of fires do not respond well when plain water is used to try and extinguish them. In fact, in some classes of fire, water actually makes things worse. The best example of this are Class B fires (Flammable Liquids like Gas and Oil).
The 3 things needed for fire combustion to sustain itself are Heat, Oxygen, and Fuel (the Fire Triangle). Removal of any one element in the triangle will stop combustion. The aim of all firefighting additives is to remove one or more of those elements. Since it is difficult or impossible in many cases to remove the source fueling the fire, most additives are focused on removing heat and/or oxygen from the fire to halt combustion.
While there are many water additives, the most well-known example is AFFF.
Aqueous Film Forming Foams (AFFF) is awater based foam that is used on Class B (flammable liguid) fires. It's commonly used in airport firefighting vehicles as fuel fires are very difficult to extinguish. The foam expands rapidly when it hits the air, coats the surface of the fuel causing the fire, thus cutting off oxygen. It also cools it, thus taking away heat.
Alcohol Resistant Aqueous Film Forming Foams(AR-AFFF)
These are other types of foam that are used on alcohol type fires

Production process of Waterproofing modified bitumen membrane?
The production process of waterproofing modified bitumen membrane typically involves mixing bitumen with polymers or additives to improve its performance. This mixture is then heated to a specific temperature and applied onto a carrier sheet. The membrane is then cooled and may undergo further treatments to enhance its waterproofing properties before it is packaged and shipped for use.
What homemade additive can you add to gasoline to get better mileage?
Fuel additives are used to improve an automobile's environmental performance and increase its mileage. Some homemade fuel additives are ethanol and a mixture of acetone, xylene and cycle oil.
What are the fuel additives in rocket engines?
Fuel additives in rocket engines are substances added to propellants to enhance performance, stability, and efficiency. Common additives include stabilizers to prevent decomposition, oxidizers to support combustion, and agents that reduce freezing points or improve combustion characteristics. Some formulations also incorporate additives to minimize corrosiveness or reduce the formation of harmful byproducts. These additives help optimize engine performance and ensure safe and reliable operation during launch and flight.
What additives are in Murphy's gasoline?
Murphy's gasoline contains additives such as detergents, corrosion inhibitors, and stabilizers to improve engine performance, reduce deposits, and protect against corrosion. The exact formulation may vary depending on the specific gasoline blend.
What rocket engines can obtain forward momentum with fuel additives?
Rocket engines that can obtain forward momentum with fuel additives include hybrid rocket engines, which use a combination of solid and liquid or gaseous oxidizers. These engines can enhance performance and efficiency by introducing additives like nitric oxide or hydroxyl-terminated polybutadiene (HTPB) into the fuel mix. Additionally, some liquid rocket engines utilize additives in their propellants to improve combustion characteristics and thrust. Overall, the use of fuel additives can optimize engine performance and enable more efficient propulsion.
What is cement slurry and types?
Cement slurry is a mixture of cement, water, and sometimes additives that is used in construction and oil well cementing to create a fluid that can be easily pumped and set to form a solid mass. The primary types of cement slurry include neat cement slurry, which consists of just cement and water, and various modified slurries that incorporate additives for specific properties, such as retarders, accelerators, or additives to enhance fluid loss control and improve bonding. Additionally, there are lightweight slurries, which use lightweight aggregates or additives to reduce density, and high-performance slurries designed for specialized applications in extreme conditions.
If you had to introduce lubrication to your polymers compound what would you add?
For lubrication of polymers, common additives include silicone oils, mineral oils, or polytetrafluoroethylene (PTFE) powders. These additives help reduce friction between polymer components and improve their processing or performance characteristics.
What type of thinset should be used for installing ceramic tile?
For installing ceramic tile, it is recommended to use a modified thinset mortar. This type of thinset has additives that improve adhesion and flexibility, making it ideal for ceramic tile installation.

What is proprietary additives?
Proprietary additives are specialized chemical compounds or substances developed and owned by a specific company for use in their products. These additives are often designed to enhance performance, improve safety, or provide unique benefits that differentiate the company's offerings from those of competitors. Because they are proprietary, the exact formulations and manufacturing processes are typically kept confidential to maintain a competitive advantage.
What is the difference between additives and admixtures?
Additives are substances added to a material to improve or alter its properties, while admixtures are specific types of additives used in concrete to modify its properties. Admixtures are typically used in construction to enhance the performance of concrete, such as improving workability, strength, or durability.
