PBAT (BK900)


Capacity: 60Kt/year


PBAT is a semi-aromatic biodegradable polymer and is produced by polycondensation of 1,4-butanediol (BDO), adipic acid (AA) and purified terephthalic acid (PTA). It has the characteristics of both PBA and PBT, and has good ductility and elongation at break. PBAT offers a valuable combination of technical properties with its exceptional toughness, durability, and good processibility. PBAT polymers are not only biodegradable but also compostable, so the use of PBAT can fight against white pollution. The major application for PBAT is in plastic bag production, in particular shopping bags and garbage bags, followed by food packaging, and mulch/agricultural film.
