More Information
Summary:The present disclosure relates to a powder comprising particles of a fluoropolymer, wherein the particles have an average particle size (dso) in a range from 20 to 100 micrometers, an average particle sphericity greater than 0.8 when measured according to the test method described in the experimental section, and wherein the powder has a bulk density no greater than 2000 g/l when measured according to DIN EN ISO 60:2000-1 and a powder flow time no greater than 20 seconds per 100 ml when measured according to DIN EN ISO 12086:2006-1.According to another aspect, the present disclosure is directed to a process of manufacturing such powder and uses thereof. In still another aspect, it is provided a three-dimensional article obtained by sintering such powder.
