polyarylene sulfide resin particulate, polyarylene sulfide resin particulate mixtures, methods of producing polyarylene sulfide resin particulate and three-dimensional modeling

摘要

polyarylene sulfide resin particulate, characterized in that the average particle diameter is more than 1 µm to 100 µm, the uniformity is 4 or less, the melt viscosity measured at 300 ° c and the shear rate is 1216 sec-1 is 150 to 500 pa · s and the recrystallization temperature, defined as the peak heat generation temperature at the time of crystallization by cooling from 340 ° C to 50 ° C to 20 ° C / min using differential scanning calorimeter, is 150 to 210 ° C. A suitable polyarylene sulfide resin particulate can be efficiently supplied as a powder material to produce three-dimensional modeling by means of a three-dimensional powder sintering printer.
