|---|
| PLA is a biobased polymer derived from natural resources and offers a significant reduction in carbon footprint compared to oil-based plastics. Luminy L105 is a high heat, high flow PLA homopolymer suitable for thin wall 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.&& |
