AFFF 6% plus
Fomtec AFFF 6% Plus is an aqueous film forming concentrate (AFFF) consisting of fluorocarbon and hydrocarbon surfactants blended with various solvents, preservatives and stabilizers. The foam forms a film of water that quickly cuts off the oxygen supply and extinguishes the fire. The foam expands, which the film is released, forming a stable blanket that prevents the release of flammable vapors and cools the fuel surface, extinguishing the fire and preventing re-ignition. The low surface tension of the aqueous foam allows the water film, although heavier than the burning liquid, to float on the liquid surface. Fomtec AFFF 6% Plus should be used at a 6% ratio (6 parts concentrate in 94 parts water) in brackish, fresh or seawater. It can also be stored as a premix solution in fresh water.
Applications
Fomtec AFFF 6% Plus được thiết kế để sử dụng cho đám cháy nhiên liệu hydrocacbon loại B như dầu, diesel và nhiên liệu hàng không. Nó có thể được sử dụng với cả thiết bị xả hút và không hút.
Fomtec AFFF 6% Plus đặc biệt phù hợp bất cứ khi nào cần thiết phải hạ gục đám cháy nhanh. Nó tương thích với tất cả các loại bột hóa chất khô và có thể được sử dụng trong các hệ thống tác nhân kép dạng bột / bọt.

Environmental impact Formtec AFFF 6% Plus is formulated using raw materials specially selected for their fire and environmental resistance. Formtec AFFF 6% Plus is biodegradable. However, handling of concentrated solution or foam spills should be done in accordance with local regulations. Normally sewage systems can handle foam solutions based on this foam concentrate, but local sewer operators should be consulted in this regard. This product does NOT contain PFOS or PFOA. Full details will be found in the Material Safety Data Sheets (MSDS). Storage / Shelf life Stored in its original, intact packaging, the product will have a long shelf life. Shelf life above 10 years will be found in temperate climates. As with all foams, shelf life will depend on temperature and storage conditions. If the product is frozen during storage or transportation, thawing will render the product fully usable. Synthetic foam concentrates should only be stored in stainless steel or plastic containers. Since electrochemical corrosion can occur at joints between dissimilar metals when they come contact with foam concentrates, only one metal should be used for pipes, fittings, pumps and tanks that can be used. used in the storage of foam concentrates.
