Polylactide (PLA)

Alternative and trade names
Ingeo™, BioFlex®, Purapol®


PLA is a biobased polymer derived from natural resources and offers a significant reduction in carbon footprint compared to oil-based plastics. It is a high heat, medium flow PLA homopolymer suitable for injection molding and fiber spinning. Compared to standard PLA, these PLA homopolymers have higher melting points and an increased rate of crystallization. As a result, compounds containing PLA homopolymers are suitable for the production of semi-crystalline parts, which exhibit a higher temperature resistance.
