The polyol IXOL^® M125 is a halogenated aliphatic polyether diol. Due to its low functionality, IXOL^® M125 is particularly suited for one component polyurethane (PUR) foams or for polyisocyanurate (PIR: PUR foams modified with isocyanurate structures) foams to meet high standards in fire safety. Being a reactive compound, IXOL^® M125 polyol guarantees a permanent flame retardant effect since the halogens are chemically bound to the final polymer.

IXOL^® M125 has been manufactured in our Tavaux plant (France) for about 20 years. As a mature product the manufacturing process is proven and runs totally under computer control, which ensures optimum and constant quality. Furthermore the plant is certified according to ISO 9002 standard.

The polyol IXOL^® M125 is compatible with all usual polyols and with flame retardant additives such as for example phosphoric acid esters. IXOL^® M125 has a good premix stability in preformulated systems, even if stored for a longer time. The use of IXOL^® M125 therefore offers considerable flexibility in formulation.

Nevertheless, formulators and users are advised to check that their formulations or the properties of their resulting foam do not alter with time, when long term stability of the blends is required.

IXOL^® M125 is a low viscous polyol at room temperature which enables an easy processing or use in special application such as one component foams (OCF).

Product use

IXOL^® M125 imparts advantages as a high performance flame retardant in the following main applications: 

• One component foams: IXOL^® M125 used in combination with polyether polyols or with polyester polyols gives a foam achieving a high flame suppression standard, for example the B2 classification according to the German standard DIN 4102.
   
• PIR foams blown with HCFCs such as Solkane 141b or hydrocarbons such as n-pentane: The use of IXOL^® M125 allows a reduction of the isocyanate index and therefore has a positive impact on the foam friability.
   
• Adhesives: IXOL^® M125 improves the fire performance of PU based adhesives.
   
• Special systems: IXOL^® M125 can be used in combination with other polyols including the polyol IXOL^® B251. The association of those two brominated polyols can help to reach a good compromise between the fire properties and the mechanical properties of the foam.
