General description

Poly(butylene succinate) (PBS) is a biodegradable, aliphatic polyester polymer that has properties similar to polypropylene. PBS 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 packaging, agriculture, and medicine.

Application

  • Recyclable and Sustainable Packaging - including food packaging, films, bags, or boxes
  • Cosmetics
  • Disposable products such as tableware
  • Agriculture - delayed release materials for fertilizer or pesticides
  • Drug delivery and implants

Features and Benefits

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