Abstract: 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.

Abstract: Crosslinked silicone foams are provided that can be substantially free of chemical blowing agents or byproducts thereof. These foams can be prepared from polymerizable silicone compositions that include an MQ-water cluster including a silicate MQ resin and a quantity of water dispersed in the silicate MQ resin and a silicone fluid, wherein the MQ-water cluster and silicone fluid collectively provide a inverted emulsion having a continuous and a discontinuous phase, the continuous phase including the silicone fluid and the discontinuous phase including the MQ-water cluster. The foams can be made by dispersing water into a silicate MQ resin to provide an MQ-water cluster; dispersing the stabilized MQ-water cluster into a silicone fluid to obtain an inverted silicone emulsion having the MQ-water cluster as a discontinuous phase and the silicone fluid as a continuous phase; foaming the silicone emulsion by evolving the water in the MQ-water cluster to provide a cellular structure; and polymerizing the silicone emulsion.

Abstract: Even when a mixture resin of virgin resin and recovered resin material is used as a resin material for molding, a stable, high-quality foam-molded article with excellent impact resistance is produced at low cost. For this, the resin material that is used includes a mixture resin of recovered resin material obtained by pulverizing a resin material solidified after melting, and virgin resin without thermal history of melting, and a foaming agent added to the mixture resin. The resin material is a mixture of a polypropylene-based resin and a polyethylene-based elastomer.
