PLA: Poly(lactic acid)
If you have a PLA need, please complete this form with information on your volume, location and lead time requirements, and your target application.
PLA is an aliphatic thermoplastic polyester produced from sugar or corn via fermentation a fermentation process that produces lactic acid as an intermediate. It is considered a promising alternative to petrochemical-derived polymers in a wide range of commodity and engineering applications. Of the bioplastics, it is the second most abundantly produced after starch blends.

PLA is one of the most widely used biopolymers in replacing fossil-fuel-based plastics on account of its good mechanical and processing properties. Its tensile strength and elastic modulus are comparable with those of poly(ethylene terephthalate) (PET) and polystyrene (PS).
PLA is inherently brittle, with less than 10% elongation at break and relatively low impact strength, which can be enhanced through blending. It also has a low glass transition temperature (Tg). It is currently predominantly used in packaging with increasing adoption in other areas such as electronics, textiles and consumer goods is growing.
