Title: Innovations of Inventor Ling Hu
Introduction
Ling Hu is a notable inventor based in Westlake, OH (US), recognized for his contributions to the field of polyvinyl halide compounds. With a total of nine patents to his name, he has made significant advancements in materials that enhance thermal conductivity and flexibility.
Latest Patents
One of his latest patents is for a thermally conductive polyvinyl halide. This innovative compound includes polyvinyl halide resin, natural or synthetic graphite in flake or spheroid form, and at least 0.5 weight percent of epoxidized vegetable oil. The careful selection of graphite and epoxidized vegetable oil allows for improved thermal conductivity while maintaining other desirable properties. This compound is particularly useful in applications requiring flame retardance and effective thermal management, such as in LED lighting fixtures, where it can replace traditional die cast or extruded aluminum heat sinks.
Another significant patent involves a flexible polyvinyl halide used for injection over-molding. This compound, either alone or alloyed with thermoplastic polyurethane, serves as a flexible layer for over-molding a rigid polymer substrate. The choice of calcium carbonate for the overmolding layer enhances peel strength, ensuring cohesive failure of the flexible layer rather than adhesive failure at the interface with the rigid substrate.
