Flamax Firex is a highly efficient BC-type Firex dry chemical powder. It is a potassium bicarbonate–urea complex reaction-based powder. Additives are mixed to make the powder free-flowing, moisture repellent, and weather resistant. It is effective on fires involving ordinary combustible materials, such as flammable liquids, gases, and energized electrical equipment. Special high-performance free-flowing additives and hydrophobic agents are also added to ensure the best water repellence and minimize the risk of powder caking during storage. It is suitable for use in high-risk areas such as refineries, chemical plants, and airfields where superior fire extinguishing capabilities are of paramount importance. The powder has a good electrical insulation value & discharge performance (fluidity.) The powder has good stability with more than a 5-year shelf life.
