摘要： Polymer extruded or expanded foams that contain modifier-free nanoclays are provided. The addition of modifier-free nano-clays to extruded or expanded foam products improves the thermal properties, mechanical properties, and fire performance properties. Water or a water-containing compound is used as a carrier for the modifier-free nanoclays. The final foamed products may be utilized in building application such as foamed insulation products and in underground applications such as highway insulation. A preferred modifier-free nanoclay is Na+MMT. Modifier-free nanoclay particles may be injected into a polymer during an extrusion foaming process. In another embodiment of the invention, polymer beads containing water/nanoclay particles are formed using inverse emulsion/suspension polymerizations and expanded or extruded into a foamed product. In a further embodiment, a modifier-free nanoclay particle is encapsulated in a super-absorbent material, which may be used in an expanding or extruding process.

摘要： The present invention is directed to thermo-expandable microspheres and to the expanded microballoons, microcellular foam or foamed composite material that results upon heating the microspheres. The thermo-expandable microsphere of the present invention is characterized by having a polymeric wall surrounding one or more pockets or particles of blowing agent or propellant within the microsphere. The polymeric wall may have reactive functional groups on its surface to give a fusible microsphere. When the microspheres are heated, they expand to form microballoons comprising polymeric shells surrounding one or more internal gaseous voids, and when the microspheres are expanded while in contact with each other, a microcellular foam may be formed. The foam consists of a plurality of microballoons fused together, optionally aided by functional groups present on the surface of the heated microspheres that act to crosslink the material. When microspheres are mixed with a matrix, which can optionally react with functional groups on the microsphere surface, and the resulting combination is heated, the microspheres expand to give a foamed composite material in which the microballoons may be fused or chemically crosslinked to the matrix.
