Intumeszenz-Beschichtungen

So bleibt Stahl kühl

Ein Intumeszenz-System ist eine Kombination aus mehreren Verbundstoffen, die im Falle eines Brandes aufgrund des Temperaturanstiegs gemeinsam reagieren und einen Kohlenstoffschaum bilden. Dieser Schaum erreicht eine Dicke, die 10 bis 100 Mal so dick ist wie die ursprünglich aufgetragenen Beschichtung, und die das Trägermaterial durch seine geringe Wärmeleitfähigkeit isoliert. Dieser Vorteil kann insbesondere für Stahlrahmenkonstruktionen sinnvoll sein, da sie im Brandfall ihre strukturelle Stabilität verlieren können, wenn die Temperaturen 500 °C übersteigen. Solche Konstruktionen befinden sich üblicherweise in Flughäfen, Einkaufszentren, Krankenhäusern und Bürokomplexen.

Als Hauptlieferant des wichtigen Inhaltsstoffes Ammoniumpolyphosphat verfügt Clariant über umfassende Erfahrungen in Bezug auf Rohstoffe für Intumeszenz-Beschichtungen und in der Entwicklung von Formulierungen für wasser- oder lösemittelhaltige Intumeszenz-Beschichtungen.

Die Exolit® AP Produkte sind feine weisse Pulver auf Ammoniumpolyphosphat-Basis.

 

Service für unsere Kunden

Clariant ist seit über 30 Jahren führender Anbieter von Flammschutzmitteln auf Phosphorbasis. Dadurch sind wir in der Lage, unsere Kunden perfekt zu unterstützen und geeignete Intumeszenz-Formulierungen für sie zu entwickeln.

In unserem Labor in Knapsack (Deutschland) können wir die Leistung verschiedenster Formulierungen in Standard Brandprüfungen testen. So unterstützen wir unsere Kunden bei der Entwicklung neuer Formulierungen, damit sie den neuen Standards und Herausforderungen in Bezug auf Brandschutzbestimmungen gerecht werden.

Relevante Produkte

  • Exolit® AP Produkte

    • Exolit® AP 420

      Exolit AP 420 is an approx. 45 % clear to cloudy aqueous solution of a short-chain ammonium polyphosphate. Mehr

    • Exolit® AP 422

      Exolit AP 422 is a fine-particle ammonium polyphosphate (phase II) produced by a special method. The product is largely insoluble in water and completely insoluble in organic solvents. It is colourless, non-hygroscopic and non-flammable. Mehr

    • Exolit® AP 423

      Exolit AP 423 is a fine-particle ammonium polyphosphate produced by a special method. The crystal modification is phase II. The product is largely insoluble in water and completely insoluble in organic solvents. It is a white powder, non-hygroscopic and non-flammable. Mehr

    • 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. Mehr

    • 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. Mehr

The carbon foam layer so formed protects the polymer through its heat-insulating effect and reduces further oxygen access. Mehr

    • 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. Mehr

    • 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.

      You will find Exolit® AP 755 now as Exolit® IFR 36. Sie finden Exolit® AP 755 nun unter Exolit® IFR 36. http://www.clariant.com/de/Solutions/Products/2014/06/05/13/42/Exolit-IFR-36 Mehr

    • Exolit® AP 760

      Exolit AP 760 is a non-halogenated flame retardant based on ammonium polyphosphate, which develops its effectiveness through phosphorus / nitrogen synergism. When incorporated into thermoplastics, it exhibits high processing stability. Exolit AP 760 differs in its mode of action from chlorine- or bromine-containing flame retardants by achieving its effect through intumescence. The thermoplastic material foams on exposure to flame. The carbon foam layer so formed protects the polymer through its heat-insulating effect, reduces further oxygen access and prevents dripping of the thermoplastic. Mehr

    • Exolit® AP 765 (TP)

      Exolit AP 765 is a non-halogenated flame retardant based on phosphorus and nitrogen synergism. The product achieves its flame retardant effect through intumescence. The thermoplastic material foams and crosslinks on exposure to flame and forms a stable char at the surface acting as a barrier. The protective layer provides a heat-insulation effect, reduces oxygen access and prevents dripping of molten polymer. Mehr

RoHS 2.1 - the Story Continues

The EU Directive on the Restriction of certain Hazardous Substances in Electric and Electronic Equipment (RoHS, 2002/95/EC) was originally published in 2003. It banned the heavy metals cadmium, lead, chromium(VI), mercury as well as the brominated flame retardants PBBs and PBDEs in E&E equipment. There is a legislative mandate that the directive is revised regularly, and after long discussions in particular on any additions to the list of restricted substances, a “re-cast” was published as 2011/65/EU. Although there were strong proponents of further bans on halogenated flame retardants, no new substance bans (Annex II) were put in place Mehr

Cutting Edge Flame Retardants for Thin Parts

Miniaturization is the creation of ever-smaller scales for mechanical, optical, and electronic products and devices. Miniaturization is a continuing trend in the production of such devices. Items which take up less space are more desired than items which are bigger and bulkier because they are easier to carry, easier to store, and much more convenient to use. Mehr
