Thermal insulation is part of the state-of-the art way of construction, be it for individual houses, commercial complexes, industrial structures or public buildings.
In this area rigid polyurethane foams (PUR) are established as the most efficient thermal insulation material that is manufactured on industrial scale. The outstanding characteristics of this cellular material are becoming nowadays a major item because ot he necessity to protect our environment, in particular by reducing the emmissions of greenhouse gases through a lower energy consumption (reduction of carbon dioxide emissions).
For obvious safety reasons, rigid polyurethane foams must comply with various standardized tests defined by national or international institutions. IXOL B 251 gives the possibility to produce rigid polyurethane foams which can achieve the requirements of many European and American tests. Rigid polyurethane foams formulated with IXOL B 251 can in particular pass the following tests.
The polyol IXOL B 251 is compatible with all usual polyols and with non reactive flame retardants such as phosphoric acid esters. It presents moreover useful synergism with these compounds.
The use of IXOL B 251 offers therefore considerable flexibility in formulation.
Nevertheless, system houses are advised to check that their formulations do not alter with time whenever a long term stability of the polyol blend is required.
The graph shown in the datasheet indicates for PUR formulations (ISO index 110) the typical concentration range of IXOL B 251 that are needed in formulated polyol blends in order to achieve different levels of fire retardancy.
Furthermore, formulations containing the polyol IXOL B 251 can be used in the most varied processing techniques such as e.g.:
- Injection moulding in "sandwich" plates for the manufacture of cladding panels or elements for cooling chambers and cold stores
- Continuous production of panels (laminates) according to the so-called "double conveyor" technique
- Manufacture of blocks which can be shaped or cut into plates
- In-situ projection or cast molding for roof tightening and insulation, vertical or under-face insulation.
For one-component foams and high index polyisocyanurate foams, we also offer IXOL M 125, a diol with a lower hydroxyl number and a lower viscosity. A specific documentation on this IXOL type is available on request.
