PLA vs Traditional Plastics

Thanks to its technical properties, pure PLA can compete with PET and PS. To adjust or modify its characteristics, the use of compounds and/or additives is possible.
PLA vs Traditional Plastics

PLA comparison with traditional fossil-based plastics

Pure PLA as a stand-alone resin can compete with PET and PS. Regarding HDPE, PP, rigid PVC, PS (choc), PA, ABS, and PC, PLA would need to be additivated and/or processed into a compound to achieve similar physical performances depending on the final application. 

Limitations of pure PLA 

Solutions 

Brittleness 

Impact modifiers, plasticisers 

Low crystallisation rate/crystallinity 

Nucleating agent 

Limited heat resistance (if amorphous) 

Fillers, nucleating agent, blends

Low hydrolysis resistance 

Anti-hydrolysis agent

PLA vs Traditional Plastics

PLA technical limitations and solutions

Overall, while pure PLA has many key features, its medium heat resistance, brittleness, and sensitivity to moisture are limitations that must be considered when evaluating its use in various markets and applications. The development of new PLA-based compounds and the use of a broad range of additives allow for the improvement of the physical properties of pure PLA resins.
