Title: Innovations of James Chi-Hwi Wang
Introduction
James Chi-Hwi Wang is a notable inventor based in Kendall Park, NJ (US). He has made significant contributions to the field of materials science, particularly in the development of advanced films and molding techniques. With a total of 3 patents to his name, Wang continues to push the boundaries of innovation.
Latest Patents
One of Wang's latest patents is for a multi-layer barrier film. This delamination-resistant film comprises a core layer of vinyl alcohol polymers or copolymers, such as polyvinyl alcohol or ethylene vinyl alcohol. Adhered to the core layer are one or more layers of a partially hydrolyzed vinyl acetate polymer or copolymer, which possess functional groups that ensure strong adhesion to the core layer. The core layer provides an excellent oxygen barrier, while the adjacent layers protect it from degradation due to exposure to water vapor. The film can be prepared using coextrusion techniques. Another significant patent involves a transfer blow molding technique. In this process, parisons are injection molded using a cooled cavity and a relatively hot core pin to prevent the formation of residual internal stress in or near the inner surface of the parison. The parison is promptly transferred while still hot from the injection mold to a temperature conditioning station, allowing for a desired temperature distribution. The temperature-conditioned parison is then highly molecularly biaxially oriented as it is blow molded.
