Title: Innovations by Jie Li: A Pioneer in Expanded Polyester Materials
Introduction
Jie Li is an accomplished inventor based in Zofingen, Switzerland. He has made significant contributions to the field of materials science, particularly in the development of expanded polyester materials. With a total of 3 patents to his name, Jie Li continues to push the boundaries of innovation in his field.
Latest Patents
One of Jie Li's latest patents is focused on the extrusion expansion of low molecular weight polyalkylene terephthalate for the production of expanded beads. This process involves the extrusion expanding of resins and underwater pelletizing of melt threads. The resulting beads exhibit a composite structure and are characterized by an intrinsic viscosity (IV) of 0.69 dl/g or more, along with a melt viscosity of higher than 300 Pa·s.
Another notable invention by Jie Li relates to ductile expanded polyesters that possess high impact resistance. This invention involves expanded polyester materials made from a polyester/acrylic elastomer blend, which enhances ductility and impact resistance while maintaining the compression strength and shear strength/modulus of the polyesters. The addition of a non-reactive/reactive acrylic mixture as a blend partner improves melt strength during the expansion process, leading to better impact resistance in expanded aromatic polyester materials.
