Вспучивающиеся покрытия

Помогая стали оставаться холодной

Вспениваемая система — это сочетание различных составов, которые в случае пожара дают совместную реакцию под действием большой температуры, образуя углеродную пену. Эта пена в 10–100 раз толще исходного покрытия и изолирует материал подложки благодаря своей низкой термопроводимости. В частности, для конструкций со стальной рамой она может быть жизненно необходима, поскольку во время пожара при температуре более 500 °C они могут терять свою конструкционную прочность. Примеры таких зданий — это аэропорты, торговые центры, больницы и офисные комплексы.

Как главный поставщик ключевого ингредиента, полифосфата аммония, Clariant имеет обширный опыт в вопросах сырья для вспениваемых покрытий и разработки их рецептур на водной основе и на основе растворителей.

Основной компонент Exolit® AP — это мелкие белые порошки на основе полифосфата аммония.

Услуги для наших заказчиков

Clariant более 30 лет является ведущим поставщиком ингибиторов горения на основе фосфора. Наша позиция заключается в поддержке своих заказчиков путем разработки подходящих рецептур вспучивающихся покрытий.

В своей лаборатории в г. Кнапзак, Германия, мы имеем возможность сравнивать эффективность ряда различных рецептур при испытаниях на воспламеняемость. Тем самым мы оказываем своим заказчикам поддержку в разработке новых рецептур, соответствующих новым стандартам или задачам в области пожарной безопасности.

    • Exolit® AP 462

      Exolit AP 462 is a product based on ammonium polyphosphate. The crystal modification is phase II. It is manufactured from ammonium polyphosphate by micro-encapsulation with melamine resin according to Clariant’s own method. Exolit AP 462 is a fine-particle white powder with very low solubility in water, even at elevated temperatures. It is completely insoluble in organic solvents. The product is non-hygroscopic and non-flammable. Press the button "Print this page" to download the Product Data Sheet. Больше

    • Exolit® AP 740 F

      Exolit AP 740 F is a white free flowing powder. It is a non-halogenated additive flame retardant based on ammonium polyphosphate which develops its effectiveness through phosphorus/nitrogen synergism. Exolit AP 740 F differs in its mode of action from chlorine or bromine containing flame retardants by achieving its effect through intumescence. The flame retarded material foams on exposure to flame. The carbon foam layer so formed protects the polymer through its heat-insulating effect and reduces further oxygen access.

    • Exolit® AP 742

      Exolit AP 742 is a non-halogenated, additive flame retardant based on ammonium polyphosphate, which develops its effectiveness through a phosphorus/nitrogen synergism. Exolit AP 742 differs in its mode of action from other flame retardant technologies (e.g. chlorine- or bromine-containing flame retardants and minerals) by achieving its effect through intumescence. The flame retarded material foams on exposure to flame. The carbon foam layer so formed protects the polymer by its heat-insulating effect and reduces further oxygen access.

    • Exolit® AP 750

      Exolit AP 750 is a non-halogenated flame retardant based on ammonium polyphosphate as main component, which develops its effectiveness through phosphorus/nitrogen synergism. In contrast to similar competitive material, it shows high processing stability. Exolit AP 750 differs in its mode of action from non phosphorus-based flame retardants (e. g. brominated, chlorinated or mineral FRs like ATH) by achieving its effect through intumescence. Material containing Exolit AP 750 will foam on exposure to flame. The carbon-rich foam layer so formed will protect the polymer and in many cases the substrate below through its heat-insulating effect, reduces further oxygen access and prevents dripping in case of a thermoplastic based formulation. Beyond the primary effects on fire behavior such as reduction of flame propagation rate, rate of heat release, dripping behavior, residual lengths of test specimens after flame tests etc., positive secondary fire effects such as low smoke density, no release of corrosive off-gases, lower formation of toxic smoke gases are of great interest.
