| Abstract: | The technique of preparing low density polyethylene (LDPE) using hollow glass beads that was full of N2 as gas carriers by compression molding was studied. Results showed that in the LDPE foam prepared by the technique, the bubbles distributed homogeneously, the average diameter of the bubbles was small, and the tensile strength of the material decreased slightly, but the heat conductivity decreased greatly. |
