    Abstract: Described is a process for making closed cell fluoropolymer foam, and the foam so made. The process includes subjecting a fluoropolymer resin an inert gas at a pressure higher than atmospheric to drive gas into the resin, raising the temperature of the resin to or above its softening point, and reducing the pressure while maintaining the temperature at or above the softening point of the resin, in order to expand the resin to result in closed cell fluoropolymer foam. The resin is cross-linked prior to expansion. The resulting foams can be used in various applications, such as in flotation devices and for making thermal and/or acoustic insulation.

    Abstract: Disclosed is a thermoplastic resin foam which is obtained by subjecting a thermoplastic resin composition containing a thermoplastic elastomer and an active-energy-ray-curable resin to foam molding to give a foamed structure, and irradiating the foamed structure with an active energy ray to allow the active-energy-ray-curable resin to form a cross-linked structure in the foamed structure. Also disclosed is a thermoplastic resin foam which is obtained by subjecting a thermoplastic resin composition containing a thermoplastic elastomer, an active-energy-ray-curable resin, and a thermal cross-linking agent to foam molding to give a foamed structure, irradiating the foamed structure with an active energy ray to allow the active-energy-ray-curable resin to form a cross-linked structure in the foamed structure, and heating the resulting foamed structure bearing the cross-linked structure to thereby allow the thermal cross-linking agent to form another cross-linked structure in the foamed structure.
