The foamed sheet of the present invention is a foamed sheet obtained by crosslinking and foaming a polyvinylidene fluoride-based resin composition comprising a polyvinylidene fluoride-based resin, wherein the polyvinylidene fluoride-based resin comprises a vinylidene fluoride-hexafluoropropylene copolymer, a density of the foamed sheet is not more than 180 kg/cm.sup.3, and an average cell diameter of the foamed sheet is not less than 100 μm and not more than 500 μm. According to the present invention, a crosslinked polyvinylidene fluoride-based resin foamed sheet having both good flame retardance and good flexibility and a process for producing the foamed sheet are provided.

A polymer composition may include at least one ethylene vinyl acetate (EVA) polymer; a blowing agent in an amount ranging from 2 to 18 phr; and a crosslinking agent in an amount ranging from 0.3 to 4 phr. A method includes expanding an EVA-based polymer composition to form a foam having a density ranging from 0.01 g/cm3 to 0.06 g/cm3 and a hardness ranging from 10 to 60 Shore 00.

The present disclosure describes multi-fluid kits for three-dimensional printing, materials kits for three-dimensional printing, and methods of making three-dimensional printed articles. In one example, a multi-fluid kit for three-dimensional printing can include a fusing agent and a pore-promoting agent. The fusing agent can include water and a radiation absorber. The radiation absorber can absorb radiation energy and convert the radiation energy to heat. The pore-promoting agent can include water and a water-soluble pore-promoting compound. The pore-promoting compound can chemically react at an elevated temperature to generate a gas.
