Abstract Blowing film was prepared using polyester elastomer with thermally expandable
microcapsule to investigate the optimum blowing properties and the film making
process. Physical properties including specific gravity, blowing efficiency, foaming shape,
tensile strength and elongation of polyester film were tested by varying the process condition
of temperature and revolution per minutes of the extruder. The lowest specific gravity
of 0.709 can be achieved with excellent foaming cells at 210℃ and 50 RPM conditions.
The highest tensile strength and elongation was shown at 210℃, 100 RPM and 230℃, 25
RPM conditions. However, most of the prepared polyester films showed over 1kgf/mm2 of
tensile strength which is reasonable value to use in film applications. |
