A flame-retardant rubber composition is provided which is excellent in flame retardancy and rubber properties and reduces environmental load. The flame-retardant rubber composition comprises an ethylene/α-olefin/non-conjugated diene copolymer, a hydrated metal oxide, a silane coupling agent, a plasticizer, and a cross-linking agent, wherein a carbon number of the α-olefin of the ethylene/α-olefin/non-conjugated diene copolymer is three and more, and 180 to 350 parts by mass of the hydrated metal oxide and 10 to 60 parts by mass of the plasticizer are included per 100 parts by mass of the ethylene/α-olefin/non-conjugated diene copolymer.

The invention refers to a flame-retarding and flame-blocking agent in the form of a liquid suspension that efficiently slows down the progress of fire and at the same time, blocks forest fires, acting as a chemical firebreak and as a fire extinguisher, as well as to a method of making the suspension. The application process comprises spraying the diluted aqueous suspension/solution of the invention on a strip of land, forest, or silviculture, without harming the environment, animals, agricultural products, and humans. The product acts for a long time after application, is stable for storage, effective regardless of the water used for dilution, easily dispersible in water, biodegradable without containing toxic products or releasing highly toxic gases, and free of heavy metals. The product has a synergistic action between its components, and it is intended to save lives, natural resources and heritage.

An assembly includes at least two fire protection profiles which have a hose that is made of a composite material and is filled with a fire protection material. The composite material has an inorganic fiber material which is connected to a film, and the fire protection profiles are designed such that said profiles bake together in the event of a fire. Furthermore, a method for producing a fire protection profile is provided.

A method for imparting flame retardancy to a substrate material. The method comprises adding to a substrate material a flame retardant composition. The flame retardant composition comprises at least one flame retardant salt, a nitrogen-containing compound, and optionally water. The at least one flame retardant salt comprises an ammonium salt of phosphoric acid. The ammonium salt of phosphoric acid comprises water soluble ammonium polyphosphate (APP). The water soluble ammonium polyphosphate has a total nitrogen as N from about 5 to about 15 weight percent, and a total phosphorus as P.sub.2O.sub.5 from about 30 to about 40 weight percent, based on the total weight of the ammonium polyphosphate (APP).
