| About |
|---|
| PLA is a biobased polymer derived from natural resources and offers a significant reduction in carbon footprint compared to oil-based plastics. Luminy L175 is a high heat, high viscosity, PLA homopolymer suitable for film extrusion, thermoforming or 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.&& |
