Abstract:
Various embodiments disclosed relate to melt-stabilized ultra high molecular weight polyethylene (UHMWPE), methods of making the same, and medical implants made from the same. In various embodiments, the present invention provides a method of melt- stabilizing UHMWPE. The method can include coating a solid material including UHMWPE with an antioxidant, to provide an antioxidant-coated solid material. The method can include pre-irradiatively heating the antioxidant-coated solid material to diffuse the antioxidant therein, to provide an antioxidant-diffused solid material. The method can include irradiating the antioxidant-diffused solid material, to provide an irradiated solid material. The method can include post-irradiatively heating the irradiated solid material, the heating sufficient to melt at least part of the UHMWPE, to provide a heated material. The method can also include solidifying the heated material, to provide a melt-stabilized material.

Abstract:
The invention relates to methods for lowering the melt viscosity and thereby improving heat-sealability of a polyester. The invention also relates to a method for manufacturing a heat-sealed container or package from fibrous- based, polyester-coated packaging material, and a method for heat-sealing polyester. The solution according to the invention is subjecting polyester to electron beam (EB) radiation. The lowered melt viscosity allows a lower heat- sealing temperature, and permits sealing of polyester to an uncoated fibrous surface. The preferred polyester for the invention is polylactide, as such or as blended with another polyester.
Abstract:
A method of fabricating a polishing pad includes determining a desired distribution of voids to be introduced within a polymer matrix of a polishing layer of the polishing pad. Electronic control signals configured to be read by a 3D printer are generated which specify the locations where a polymer matrix precursor is to be deposited, and specify the locations of the desired distribution of voids where no material is to be deposited. A plurality of layers of the polymer matrix corresponding to the plurality of the first locations is successfully deposited with the 3D printer. Each layer of the plurality of layers of polymer matrix is deposited by ejecting a polymer matrix precursor from a nozzle. The polymer matrix precursor is solidified to form a solidified polymer matrix having the desired distribution of voids.
