Abstract
A method of producing silicone foam includes the step of adding a mechanical foaming agent to uncured silicone. The mechanical foaming agent is a plurality of solid bodies insoluble in the silicone. The method also includes the steps of curing the silicone and removing the mechanical foaming agent as intact solid bodies from the silicone thereby providing a silicone foam.
Claims5
) A method of producing silicone foam, comprising:
- adding a mechanical foaming agent to uncured silicone, said mechanical foaming agent being a plurality of solid bodies insoluble in said silicone;
- curing said silicone;
- and
- removing said mechanical foaming agent as intact solid bodies from said silicone thereby providing a silicone foam.
) The method of claim 1, further including reusing said mechanical foaming agent to produce more silicone foam following the removing step.
) The method of claim 1, further including selecting said mechanical foaming agent from a group of materials consisting of metal, plastic, glass, cured silicone beads and mixtures thereof.
) The method of claim 3, wherein said solid bodies of mechanical foaming agent have a width/diameter between about 0.5 and about 8.0 mm.
) The method of claim 4, wherein said mechanical foaming agent is removed by pressing said solid bodies from said cured silicone.
