  • Flame retardant polyurethane foams containing biuret linkages
    Patent number: 9034936
    Abstract: Polyurethane foams are made using a biuret-modified MDI and/or PMDI as the isocyanate component. The isocyanate is characterized by having a high content of biuret-containing oligomers and, preferably, a low proportion (if any) of biuret-urea oligomers. Flexible, resilient foams made using this biuret-modified isocyanate perform well on flammability tests such as the UNI 9175 CS. E. RF4 test, even without added flame retardants.
    Type: Grant
    Filed: December 16, 2010
    Date of Patent: May 19, 2015
    Assignee: Dow Global Technologies LLC
    Inventors: Alessia Battistini, Gianluca Casagrande, Luigi Bertucelli, Alessio Sabadini
  • Self-crushing polyurethane systems
    Patent number: 9018271
    Abstract: Embodiments of the invention provide for polyurethane flexible foams that do not require a post production crushing step. These “self crushing” flexible foams neither collapse, skin peel, nor form voids upon demolding, and yet maintain excellent physical properties such as uniform cell sizes, high quality surface appearance, compression set, resistance to fatigue, etc.
