  • Method of grinding polyaryletherketones
    Patent number: 11691315
    Abstract: An improved method of grinding polyaryletherketones, providing very good yields and the production of powders of polyaryletherketones with an average diameter below 100 ?m having a narrow size distribution with few fine particles (Dv10>15 ?m). Method of grinding polyaryletherketones of apparent density below 0.9 carried out in a temperature range between 0° C. and the glass transition temperature of the polymer measured by DSC, in order to obtain powders having a particle size distribution (diameters by volume) of d10>15 ?m, 50<d50<70 ?m, 120<d90<180 ?m.
    Type: Grant
    Filed: January 12, 2021
    Date of Patent: July 4, 2023
    Assignee: ARKEMA FRANCE

  • Polyamide powder and method for coating an object by melting said powder
    Patent number: 9550914
    Abstract: The present invention relates to a coating composition in the form of a loose powder including the following by weight: 50% to 99.99% of polyamide powder, and 0.01% to 0.5% of polypropylene glycol, out of the total weight of the composition. The present invention relates in particular to a coating composition in the form of a powder including the following by weight: 50% to 99.9% of polyamide powder, 0.01% to 10% of at least one pigment and 0.01% to 0.5% of polypropylene glycol, out of the total weight of the composition. The present invention relates in particular to the use of said composition in methods for coating objects, in particular metal, by means of stuccoing.
