Abstract: Disclosed herein is a foamable resin composition for a foam sheet including polylactic acid resin particles, each of the particles having a particle size of about 1 ?m to about 100 ?m. A process for preparing a particulate polylactic acid resin includes: introducing a polylactic acid resin and then forming a molten polylactic acid spray solution; and injecting the molten polylactic acid spray solution by a melt spray method and simultaneously cooling the molten polylactic acid spray solution to obtain a particulate polylactic acid. In addition, disclosed herein is a process for preparing a foam sheet using the foamable resin composition for a foam sheet including a polylactic acid resin.

Abstract: A thermoplastic elastomer (TPE) resin powder includes spherical particles of a thermoplastic elastomer resin that have an average particle diameter of 50 ?m to 300 ?m.

Abstract: Disclosed is a polymer powder having an average particle diameter of 20 ?m to 300 ?m, with a particle diameter of less than 10 ?m of 10 mass % or less, and a particle diameter of greater than 300 ?m of 10 mass % or less. Further, disclosed is a method for preparing a polymer powder, comprising: forming a melt of a polymer; introducing a supercritical fluid into the melt of the polymer to form a mixed composition; and spraying the mixed composition to prepare the polymer powder.
