Baxenden Announces a range of HCFC-Free Foams

Following a two year research programme Baxenden Chemicals is offering a full range of HCFC [hydrochlorofluorocarbon] -free polyurethane systems. The range meets the varied applications of the flexible, integral skin, RIM and rigid polyurethane [PU] foam markets.

Following a two year research programme Baxenden Chemicals is offering a full range of HCFC [hydrochlorofluorocarbon] -free polyurethane systems. The range meets the varied applications of the flexible, integral skin, RIM and rigid polyurethane [PU] foam markets.

A complete range of polyisocyanurate [PIR] foams are also included in Baxenden's portfolio of zero ozone depletion systems.

Rod Bicknell, Technical Sales Manager at Baxenden's Polyurethane Systems Division, explains: "As a system house we have undertaken a rigorous HCFC replacement programme to satisfy the requirements of the legislation and the technical and economic needs of a wide customer base. The products have been directed at UK and European markets.

"The various demands of thermal insulation legislation and standards, the specific processing equipment required and a cost driven solution for the use of replacement HFCs [hydrofluorocarbons] have been met on target."

Where the thermal insulation requirement is the prerequisite HFC and hydrocarbon technologies are now available to provide technical solutions. Lambda values [thermal conductivity] are equivalent to those available with the current HCFC technology.

If thermal insulation is not the primary specification, a range of co-blown polyurethane systems, including HFCs, hydrocarbons and water, are now available. The range offers a cost effective solution together with specific processing and equipment requirements.

2003 is the final year in which HCFCs can be used for polyurethane foam production in the European Community, in line with the directives for zero ozone depleting materials. The use of HCFCs for PU foam products, made for export to countries where the use of the blowing agents is still allowed, will continue until the end of 2009.
