  • Patent number: 11890800
    Abstract: A method of manufacturing a semi-crystalline article from at least one pseudo-amorphous polymer including a poly aryl ether ketone, such as PEKK, including a softening step, wherein the at least one pseudo-amorphous polymer is heated to a temperature above its glass transition temperature to soften the polymer, and a crystallization step, wherein the at least one pseudo-amorphous polymer is heated to a temperature between its glass transition temperature and melting temperature, the pseudo-amorphous polymer being placed on a mold during either the softening step or the crystallization step before at least some crystallization takes place. The method results in articles demonstrating increased opacity, increased crystallinity, increased thermal resistance, improved chemical resistance, and improved mechanical properties over articles formed by traditional thermoforming processes.

  • Publication number: 20210202134
    Abstract: A method of manufacturing a coated metallic wire having a polymeric coating, the method includes: dissolving at least one polymer including a poly(aryl etherketone) in at least one phenolic solvent to form a solution; contacting the surface of a metallic wire with the solution to form a coated wire having at least one layer of coating; and drying the coated wire to evaporate residual solvent.

  • Publication number: 20200276760
    Abstract: The present invention is directed to material extrusion additive manufacturing processes, including fused filament fabrication, used to manufacture improved parts, devices, and prototypes using polyetherketoneketones (“PEKK”) and polyetheretherketones (“PEEK”). Using the improved processes of the invention, PEKK or PEEK polymer readily is 3D printed by FFF such that it crystallizes slowly enough during deposition for the resulting part to remain mostly or substantially amorphous during printing and thus have low percentage and/or more uniform shrinkage per layer and little to no warping from the base during print, and yet fast enough so that the resulting part crystallizes in post-print processing without substantial or any loss of its printed structure.

  • Publication number: 20050173433
    Abstract: A two layer thermoplastic fuel container having a capacity of about 5 gallons or less is disclosed that includes an inner barrier layer of polyacetal resin in intimate unbonded surface-to-surface contact with an outer polyolefin layer operative to absorb impact and distribute an applied force, the two layers optionally being mechanically linked at one or more copular regions, but being otherwise capable of independent local displacement with respect to each other. Not having a bond between the layers allows them to move independently upon impact or when internal/external forces are applied. Also disclosed are methods for making these fuel containers.
