General description

Poly(butylene succinate-co-butylene adipate) (PBSA) is a combination of 1,4-butane diol, succinic acid, and adipic acid. It is a biodegradable, aliphatic polyester polymer that has properties similar to polypropylene and LDPE. PBSA is a sustainable replacement for petrochemical-derived plastics as it can be produced from renewable sources such as biomass. The ester group in the polymer backbone is hydrolytically degradable which makes this polymer advantageous in many applications and fields including sustainable packaging, agriculture, and medicine.

Application

  • Recyclable and Sustainable Packaging -including food packaging, films, bags, or boxes
  • Cosmetics
  • Drug delivery and implants
  • Better film forming application

Features and Benefits

  • Faster degradation
  • Thermoplastic processability
  • Sustainable alternative to petroleum based polymers
  • Excellent biodegradability
