ABSTRACT:
Polyvinylidene fluoride resin powder for melt molding, which exhibits such particle size distribution characteristics that the average particle diameter (D50) is 80 to 250 μm, the proportion of resin powder having a particle diameter of at most 45 μm is at most 15.0% by weight, and the proportion of resin powder having a particle diameter of at least 355 μm is at most 10.0% by weight, and has a bulk density of 0.30 to 0.80 g/cm3and an angle of repose of at most 40°, and a process for producing a molding, which comprises feeding the resin powder to an injection molding machine or extrusion molding machine, melting the resin powder, and injecting the resin melt into a mold.
