Problems solved by technology

[0004] Polyester materials have the advantages of outstanding chemical resistance, heat resistance, excellent mechanical strength, electrical insulation properties and thermal stability, and are widely used in the fields of electronics, automobiles, and home appliances. It is necessary to further improve the mechanical properties and processing properties; in order to increase the mechanical properties of materials in polymer processing, it is often necessary to add a second or even a third component to it. The influence of these multiple factors often makes it difficult to balance the strength and toughness of the material, thus limiting the development of blending modification
