樹脂パウダー
Document Type and Number:
Japanese Patent JP6642433
Kind Code:
B2
Abstract:
A resin powder having a high bulk density and an average particle size of at most 50 μm from resin particles containing a fluorocopolymer as the main component and having a melting point of 260 to 320° C., where the fluorocopolymer contains a unit containing a carbonyl group-containing group, a unit based on tetrafluoroethylene, and a unit based on a perfluoro(alkyl vinyl ether) or a unit based on hexafluoropropylene. A method of producing the resin powder by subjecting resin particles (A) having an average particle size of at least 100 μm to mechanical pulverization treatment. The resin particles (A) is made of a material (X) having a fluorocopolymer (X1) as the main component, which has a unit (1) based on a monomer containing at least one functional group selected from a carbonyl group-containing group, a hydroxy group, an epoxy group and an isocyanate group, and a unit (2) based on tetrafluoroethylene.
