The present invention is directed to compositions comprising polylactone melt, extrudate, and processes for producing a foam. In exemplary embodiments of the present invention, the processes comprise: heating a polylactone composition containing a biobased polylactone in a reaction vessel; and subjecting the polylactone composition to molding to give a foamed structure.

A composition for foam molding including: a component (A): an olefin-based polymer; a component (B): a styrene block copolymer having no chemical-bond cross-linking moiety; a component (C): a process oil; and a component (D): a foaming agent, wherein a content of the component (A) relative to a total mass of the component (A) and the component (B) is 5 to 36% by mass, and a content of the component (C) relative to 100 parts by mass of the total mass of the component (A) and the component (B) is 160 to 350 parts by mass.

The present invention provides a modified formula to make a hydrophilic foam. In some embodiments this modified formula adds a filler which causes the foam to become less absorptive, which has the benefit of making available to the skin more makeup or other products, while also providing a superior esthetic application of makeup on the skin. In other embodiments the modified formula makes the hydrophilic foam easier to clean and reduces the staining propensity of the foam. In other embodiments the modified formula uses an additive to the properties or usability of the foam in some way. Providing the filler and additive can be done in combination or separately depending on the desired benefits or properties of the foam. In some embodiments the foam is fashioned into a shape suitable for makeup application.

A composition and method for making polymeric foam is provided. The composition includes a flame retardant composition comprising brominated polymeric compounds. The resulting polymeric foams have a low bromine content of from about 0.01-0.5 wt. %, while maintaining acceptable flame retardant characteristics.

A polystyrene (PS) composition for making an extruded foam, the PS composition comprising polystyrene, a blowing agent, and an additive selected from glycerol monostearate (GMS), glycerol tri-stearate (GTS), mineral oil (MO), epoxidized soy oil (ESO), epoxidized polybutadiene, or combinations thereof. Methods of producing a low density polystyrene (PS) foam are also provided.

A method produces porous materials by expansion of polymer gels. The porous materials can be a micro- or nano-porous polymer materials.

A method of manufacturing a flexible intrinsically antimicrobial absorbent porosic composite controlling for an effective pore size using removable pore-forming substances and physically incorporated, non-leaching antimicrobials. A flexible intrinsically antimicrobial absorbent porosic composite controlled for an effective pore size composited physically incorporated, high-surface area, non-leaching antimicrobials, optionally in which the physically incorporated non-leaching antimicrobial exposes nanopillars on its surface to enhance antimicrobial activity. A kit that enhances the effectiveness of the intrinsically antimicrobial absorbent porosic composite by storing the composite within an antimicrobial container.

The invention relates to an extrusion process for the production of expandable vinyl aromatic polymer granulate comprising mixing first and second additives with first and second polymer components, respectively, in dedicated mixers.

The present invention provides a foam, a laminated foam, and a laminate that are capable of providing good walking comfort and exhibiting excellent vibration-damping properties while being lightweight and are also useful for recycling interlayer films for a laminated glass. The present invention also aims to provide a building material for housing including any of the foam, the laminated foam, and the laminate. Provided is a foam having a plurality of cells, the foam containing a polyvinyl acetal and a plasticizer and having an average aspect ratio (a/b) of cells of 1.1 or greater as calculated by a predetermined method.
