Biodegradable Plastic: Fragments of plastics that can be used by microorganisms as food and energy source & thus be converted into biomass either by aerobic on anaerobic degradation







Poly(butylene succinate) (PBS) is a biodegradable aliphatic polyester. Due to its semi-crystalline nature, thermal stability, a melting point lower than that of other commercially available biodegradable polymers, and easy processing with conventional film casting and blowing techniques, PBS is an excellent candidate for the production of biodegradable films for packaging. In particular, PBS films have good barrier properties, as PBS’s oxygen permeability (PO) is about four times lower than that of low-density polyethylene (LDPE) and about double that of PLA. (1,2,3)

PBS’s mechanical properties are similar to those of conventional polyolefins, with good tensile strength and moderate stiffness and hardness. In comparison to PLA, PBS can be characterized as a tough and resistant material.(4)

Setaş PBS has;

  • High Flexibility and Heat Resistance
  • Wide processing range:
    • extrusion, injection, thermoforming, spinning, blowing
  • Can easily be compounded
  • Good binding properties
