Title: Innovations by Inventor Sang Lee
Introduction
Sang Lee is an accomplished inventor based in Avon Lake, OH (US). He holds 2 patents that showcase his expertise in developing advanced materials. His work primarily focuses on polyvinyl halide compounds, which have significant applications in various industries.
Latest Patents
One of Sang Lee's 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 selection of types and amounts of graphite and epoxidized vegetable oil provides thermal conductivity while maintaining other desirable properties of the compound. This material is particularly useful for making end-use articles that require flame retardance and effective thermal management, such as thermally conductive materials that can replace die-cast or extruded aluminum heat sinks in industrial applications like LED lighting fixtures.
Another significant patent by Sang Lee 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 careful selection of types and amounts of calcium carbonate for the over-molding layer enhances peel strength, ensuring cohesive failure of the flexible over-molding layer rather than adhesive failure at the interface with the rigid polymer substrate.
