Abstract: Provided are heat-expandable microspheres which have high expansion performance to exhibit highly thermoresponsive expansion behavior in short heating time and the application thereof. The heat-expandable microspheres are composed of a thermoplastic resin shell and a blowing agent encapsulated therein and vaporizable by heating. The thermoplastic resin is a polymer of a polymerizable component containing a nitrile monomer, and the nitrile monomer contains acrylonitrile and methacrylonitrile in a ratio of 100 parts by weight/40 parts by weight to 80 parts by weight. The blowing agent contains a blowing agent (a) having a specific heat in the range from 0.8 J/g·K to 2.0 J/g·K. Also disclosed is a composition containing the heat-expandable microspheres and a formed product manufactured by forming the composition.

Abstract: Disclosed, among other things, are ways to manufacture reduced density thermoplastics using rapid solid-state foaming and machines useful for the saturation of plastic. In one embodiment, a foaming process may involve saturating a semi-crystalline polymer such as Polylactic Acid (PLA) with high levels of gas, and then heating, which may produce a reduced density plastic having high levels of crystallinity. In another embodiment, a foaming process may produce layered structures in reduced density plastics with or without integral skins. In another embodiment, a foaming process may produce deep draw structures in reduced density plastics with or without integral skins. In yet another embodiment, a foaming process may utilize additives, blends, or fillers, for example. In yet another embodiment, a foaming process may involve saturating a semi-crystalline polymer such as Polylactic Acid (PLA) with high levels of gas, and then heating, which may produce a reduced density plastic having high levels of crystallinity.
