FILTRATIONSMETHODE FÜR PFROPFPOLYMERPOLYOLE |
摘要 |
An index filtration method is disclosed for filtering graft polyol dispersions. The method allows for the rapid filtration of large volumes of graft polyol dispersion in an economical manner. The process can be highly automated. The resulting filtered graft polyol dispersion mainly has particles of 25 microns or smaller and is stable under a variety of conditions for at least 9 weeks. |
