Title: Wengang Hong: Innovator in Semi-Aromatic Polyamide Technology

Introduction

Wengang Hong, an accomplished inventor based in Shaoxing, China, has made significant contributions to the field of polyamide technology. With two patents to his name, he has demonstrated a commitment to innovation that addresses the needs of various industries, especially in automotive and electronics.

Latest Patents

Wengang Hong's latest patents focus on the development of semi-aromatic polyamide resins. The first patent discloses a semi-aromatic polyamide and its preparation method. This innovative resin is produced through a polymerization reaction that utilizes a diamine, a dibasic acid, and a monoacid as primary raw materials, with the incorporation of a specialized end-capping agent. The resulting semi-aromatic polyamide exhibits excellent thermal stability, a yellowness index below 20, a glass transition temperature exceeding 90° C., and a melting point above 300° C. This material is particularly suitable for use in fuel pipeline parts in automobiles as well as in the electronic and electrical sectors, including LED panels.

The second patent provides a detailed production method for the semi-aromatic polyamide. This comprehensive process involves multiple steps: starting with the formation of a slurry with an initial charge of diamine and dibasic acid, followed by dehydration and adjustments in the amine/acid molar ratio through the addition of molten diamine and a monoacid. The final step includes post-polycondensation of the pre-polymerization solution, resulting in a semi-aromatic polyamide characterized by low gel content and exceptional performance across a wide range of applications.
