Environmental concerns give phosphorus based FRS a good future
by Liz White, editor
Rising use of insulation to meet increasing demands for energy efficiency and to curb greenhouse gas emissions will fuel increase use of rigid polyurethane foam and in the process will also drive up use of flame retardants, according to Dr Oliver Vollmer, Lanxess’s director of marketing for phosphorus chemicals.
“At the same time, there are more and more regulations on FRs,” the Lanxess executive noted: “So I see a lot of moves towards phosphorus-based systems as opposed to halogen-based ones.” “Where the expectations of the market are clear is for increased demand for insulation.
That is one of the major themes of this event,” Vollmer continued, speaking 12 Oct at the CPI/UTECH meeting in Houston, Texas.
Expanding on this topic, Vollmer said: “Heating and lighting of buildings and public housing are major producers of CO2 emissions, and the trend is to cut these emissions by better insulation. This represents opportunities for insulation, whether PU or other types.” As insulation uses rises, so does use of flame retardants, Vollmer said, regardless of the specific FR solutions, phosphorus-based or otherwise.
But he feels there are very positive trends for increased use of phosphorus-based FRs, as made by Lanxess, because FRs based on halogens, including bromine, are under investigation for long-term problems of the materials produced when they burn, he…
