| Abstract: | Extrusion die swell of PP foam was investigated by HAAKE extrusion rheometer. The effect of capillary number, rotation rate of screw and temperature on the die swell of PP foam was discussed. It was pointed that the existence of bubbles had an important effect on the die swells of PP foam. Influences of the volume of the bubbles on the die swell of PP foam were analyzed. |
