Polybutylene succinate (PBS) is produced from succinic acid and 1,4-butanediol. PBS is biodegradable in soil, but otherwise displays properties similar to those of classic polyolefins such as polyethylene (PE) or polypropylene (PP).
VINNEX® greatly reduces the recrystallization rate of PBS, thereby keeping its properties constant. Depending on the VINNEX® content and grade, and by adding PLA, flexibility or stiffness can be adjusted as required. Furthermore, VINNEX® enables higher levels of organic and inorganic fillers without adversely affecting the physical properties.
By improving compatibility and melt strength, VINNEX® enables thermoforming of PBS/PLA blends. This opens up new applications such as heat-resistant containers for hot filling.
