Biodegradable polyester materials-PBAT
Product name: PBAT
Chemical name: 1, 4-Benzenedicarboxylic acid, 1, 4-dimethyl ester, polymer with 1, 4-butanediol and hexanedioic acid
CAS No.: 55231-08-8
Description
PBAT is our biodegradable, statistical, aliphatic-aromatic copolyester based on the monomers 1, 4-butanediol, adipic acid and terephthalic acid for film extrusion. It has similar properties to LDPE.
● Transparent to translucent, semi-crystalline structure with DSC melting point in the range of PE-LD: 110 –120 °C
● High ultimate elongation at break and high failure energy (dart drop)
● High, but controllable water vapour transmission rate (WVTR)
● MVR (190 °C, 2,16 kg): 2,5 – 4,5 ml/10 min.
● Good thermostability up to230 °C
● regular predrying of pellets
● Good processability on blown film lines
● Down gaging to 10 μm possible
● Weldable and printable
