Microcellular foam extrusion/blow molding process and article made thereby |
摘要 |
High-density polyethylene (HDPE) foams that are essentially free of residual chemical blowing agents and reaction-by-products of chemical blowing agent are provided. The HDPE foams can be either microcellular foams or conventional foams. The foams can be produced in extrusion, injection molding, and blow molding processes that utilize a physical blowing agent. Specific die designs useful for making high quality foams are described. |
