Polybutylene adipate terephthalate (PBAT) is a biodegradable and compostable copolymer from the group of polyesters .

Manufacturing

It is produced in a copolymerization of dimethyl terephthalate or terephthalic acid and adipic acid with 1,4-butanediol . The starting materials are currently mainly produced on the basis of fossil raw materials. However, there has also been a partially bio-based product on the market since 2009 (Ecoflex FS).

Properties and uses

PBAT can be used as a substitute for polyethylene (PE) and is particularly similar to LD-PE in its properties. It is mainly used to produce films for packaging and agriculture (e.g. mulch films).

PBAT can be used pure and as a compound with polylactic acid (PLA), polyhydroxyalkanoates (PHA), starch , lignin and cellulose .

PBAT is manufactured by BASF (ECOFLEX, ECOVIO) and JinHui Zhaolong (ECOWORLD, ECOWILL).
