摘要

Coextrusion is defined as a process in which two or more polymers are extruded and joined together in a feedblock, or die, to form a single structure with multiple layers. Coextrusion applications can range from as simple as a striped plastic beverage straw, to as complex as structures with nearly a thousand layers. The application of coextrusion is based on the viscoelastic properties of the materials combined to produce the composite structure. In both simple and complex structures, the viscosity and the elastic properties of each of the components must be considered to insure success.
