Retardantes de chamas não halogenados para soluções sustentáveis

Com as classes do Exolit®, a Clariant oferece uma extensa linha de retardantes de chamas não halogenados para itens curados a quente baseados na química do fósforo.

Os sistemas curados a quente que incluem os retardantes de chamas Exolit são aprovados nos mais rigorosos testes de fogo, mantendo boas propriedades mecânicas. Graças a essas características, os materiais podem ser utilizados em novas e exigentes áreas de aplicação. Em caso de fogo que envolva sistemas que contêm Exolit, torna-se evidente a redução na densidade da fumaça, além de não haver liberação de fumaça corrosiva, como o HCl. Veja a seguir nossas ofertas de produtos organizadas de acordo com o polímero desejado.

  • Poliuretanos (PUR)

    • 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. mais

    • 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. mais

    • 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. mais

    • 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. mais

    • Exolit® AP 766 (TP)

      Exolit AP 766 is a non-halogenated flame retardant based on phosphorus and nitrogen synergism. The product achieves its flame retardant effect through intumescence.

    • Exolit® OP 550

      Clariant’s Exolit OP 550 flame retardant can be used for flexible polyurethane foams. It is a medium-viscosity liquid and it is based on a non-halogenated phosphorus polyol with a functionality of approx. 2. The product is a reactive flame retardant that can be chemically reacted into the polymeric matrix, preventing unwanted migration from the foam. Therefore, very low fogging values can be achieved which meet the most stringent emission standards for PU flexible foams in the automotive industry. For more details see our Video about Exolit® OP 550 and 560. mais

    • Exolit® RP 6520

      Exolit RP 6520, is a brown-red paste, and is a thixotropic blend of castor oil with stabilised, microencapsulated red phosphorus. The paste form allows safe and simple handling and thus processing is made easier. The thixotropic nature of this concentrate hinders the sedimentation process and simplifies the re-homogenisation after long storage periods. mais

    • Red Phosphorus PU 6580

      Red Phosphorus PU 6580 is brown-red blend of tris(2-chloro-isopropyl)phosphate (TCPP, as a carrier) with stabilised, microencapsulated red phosphorus. The paste form allows a safe and simple handling of the red phosphorus and avoids the hazards associated when working with red phosphorus powders. The thixotropic nature of this concentrate hinders the sedimentation process and simplifies rehomogenization of the paste. As a precaution we recommend to homogenize the paste before use e.g. by agitating. mais
