Low Lambda Insulation for Building Panels
HFO-blown chemicals for the manufacture of building panels are now available from IFS, having spent two years perfecting this technology. The two main sources of concern with the new HFO molecule, namely blend stability and resin cost, have been largely mitigated in these new products from IFS. An extensive review of all polyurethane foam catalysts and silicone cell stabilisers has been undertaken in an effort to improve the long-term stability of the resin component. This has led to a series of products with proven long-term performance, available under the Envirofoam Sustain banner.
Low lambda foam products can now be produced at reasonable cost, the high price of the HFO content being partially offset by the incorporation of an environmentally-friendly biopolymer, Enviropol R201.
