Claims20
A method for manufacturing a magnetically responsive foam product, comprising the steps of:
- creating a liquid phase foam system;
- adding a magnetic fluid to said liquid phase foam system;
- blowing said liquid phase foam system into a gaseous phase foam system;
- and
- curing said gaseous phase foam system into a solidified foam product having said magnetic fluid bound therein.
A magnetically responsive foam having a magnetically responsive, three-dimensional cellular structure comprising the reaction product of a liquid-phase foam system of a polyol, an isocyanate or polyisocyanate, a catalyst and a surfactant, to which has been added a magnetic fluid and a blowing agent.
A method for manufacturing a magnetically responsive foam, comprising the steps of:
- creating a mixture of a liquid phase foam system, a blowing agent and a magnetic fluid containing a suspension of magnetically responsive particles in a liquid carrier adapted to chemically bond with a constituent or reaction product of said liquid phase foam system;
- allowing said mixture to foam into a gaseous phase foam system;
- and
- curing said gaseous phase foam system into a solidified foam product having said magnetic fluid bound therein.
