IXOL B 251 is also suitable for the development of formulations having high fire performance according to the new European standard based on the Single Burning Item (SBI) test. As example, formulations containing the polyol IXOL B 251 can lead to the manufacture of sandwich panels with a class B according to the European classification. This is the highest level that can be achieved by polyurethane foams.
The polyol IXOL B 251 does not affect the thermal insulation characteristics of the foam or its mechanical properties. It can therefore be used in various concentrations in combination with standard polyether or polyester polyols. IXOL B 251 is also suitable for manufacturing of modified isocyanurate polyurethane foams (PUIR: also known as low index polyisocyanurate foams).
