摘要： Disclosed is a method for making polystyrene foam which utilizes one or more atmospheric gases, particularly CO2, as the blowing agent in combination with a polymer processing aid (PPA), typically an ester that is relatively non-volatile at the extrusion temperature range. The blowing agent and the PPA may both be introduced into the molten thermoplastic polystyrene resin or the PPA may be incorporated in the solid source polystyrene resins. The resulting foam will be substantially free of residual blowing agent and dimensionally stable at ambient temperatures.

摘要： Disclosed is a method for making polystyrene foam which utilizes one or more atmospheric gases, particularly combinations of HFCs and CO2, as the blowing system in combination with a polymer processing aid (PPA), typically an ester that is relatively non-volatile at the extrusion temperature range. The blowing system and the PPA may both be introduced into the molten thermoplastic polystyrene resin or the PPA may be incorporated in the solid source polystyrene resins. The resulting foams will typically exhibit improved dimensional stability at ambient temperatures.

摘要： Provided are methods for producing a high strength, but easily deformed, polystyrene foam board that can endure repeatedly deformations from its original configuration into more complex curved shapes without damaging the board integrity or substantially reducing its structural strength. Also provided are rigid polystyrene foam boards produced by this method that exhibit improved bending and impact resistance while substantially retaining or improving other properties, for example, the thermal dimensional stability and fire resistance, exhibited by corresponding conventional XPS foam boards. The foamable compositions may incorporate one or more of a variety of polymer processing aids for the purpose of altering the performance of the final foam products, thereby allowing the properties of the final foam product to be customized to some degree.

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.
