Title: Yves Le Du: Innovator in Multilayer Structures
Introduction
Yves Le Du is a notable inventor based in Valailles, France. He has made significant contributions to the field of materials science, particularly in the development of multilayer structures. With a total of 2 patents, his work focuses on innovative solutions for packaging and automotive applications.
Latest Patents
Yves Le Du's latest patents include a structure comprising a binder layer that is non-delaminable with respect to a metallized substrate and peelable with respect to a polypropylene substrate. This multilayer structure consists of a metal layer or a metallized-substrate layer, a polypropylene-based binder extrusion-coated at a rate of more than 100 m/min, and optionally a polypropylene layer. The binder is made non-delaminable through heat treatment, and its composition includes a copolymer of ethylene, stretchable polypropylene, and a polypropylene functionalized by an unsaturated carboxylic acid anhydride. This innovative structure is particularly useful for the production of packages.
Another significant patent involves an article that includes a weld line based on a mixture of polyamide and polyolefin. This article is characterized by a specific ratio of viscosities of the polyolefin to the polyamide, measured at a high shear rate. The quantity of polyamide is sufficient to ensure that the elongation at break exceeds 10%. A typical application for this invention is the production of an injection molded automobile fender.
