Find out Polylactide strengths, limitations, processing, properties and applications in this profile.


Polylactide facts

  • Polylactide (Polylactic acid) (PLA) is a versatile commercial biodegradable thermoplastic.
  • These thermoplastics are based on lactic acid.
  • It is an aliphatic polyester obtained from direct polycondensational reaction and ring opening polymerization of renewably sourced (starch from corn, etc. as feedstock) lactic acid monomers.
  • PLA can be easily processed like other thermoplastics through conventional processing techniques.
  • Polylactides break down into non toxic products during degradation and being biodegradable and biocompatible, reduce the amount of plastic waste.
  • All these properties when combined with its cost effectiveness, make PLA plastics suitable for a variety of end use applications.
  • Polylactide has been able to replace the conventional petroleum based thermoplastics, thanks to the excellent combination of properties it possesses.
  • The healthcare and medical industry is making good use of polylactide in its applications due to its biocompatibility and biodegradability.
  • Packaging is another application where PLA plastics have found to be of great use.
