PLA US NatureWorks 4043D
NatureWorks 4043D (USA)
NatureWorks 4043D is a general‑purpose semi‑crystalline PLA resin with approximately 98 % L‑lactide content. It is naturally transparent / milky‑white and highly blend‑compatible, making it an ideal base resin for composite development.
Main Applications
3D‑Printing (FDM)：Signature application, widely‑recognized industry “gold‑standard” material for prototyping, functional parts and educational purposes. Films & Packaging：General‑purpose film‑grade resin for shopping bags, food packaging films and printing substrates. Injection‑molded Articles：Disposable tableware, transparent containers and various consumer goods. Biomedical Research：Base material for drug‑delivery systems and tissue‑engineering scaffolds. Composite R&D：Matrix resin compounded with cellulose, carbon nanotubes, natural fibers for high‑performance bio‑based materials.
