Product Description

Poly(L-lactic Acid) CAS 26811-96-1 For Medical And Cosmetic Application Poly-L-lactic Acid PLLA

Product Description

Poly(L-lactic acid) (PLLA) – CAS 26811-96-1

1. Description

Poly(L-lactic acid), commonly abbreviated as PLLA or Poly(L-lactide), is a semi-crystalline, biocompatible, and biodegradable polyester derived from L-lactic acid or L-lactide. It is a member of the polylactic acid (PLA) family and is widely used in medical, and sustainable material applications.

Synonyms: Poly(L-lactide), L-Polylactide, Poly[(S)-lactic acid], PLLA
Molecular formula: (C₃H₄O₂)ₙ
CAS number: 26811-96-1
Appearance: White to off-white/pale yellow pellets, granules, powder, or fibers, depending on grade.

3. Features

Biocompatible and bioabsorbable – degrades into lactic acid, which is naturally metabolized in the body.
Biodegradable – hydrolytic degradation; no enzymatic requirement in many cases.
Semi-crystalline – higher crystallinity than poly(D,L-lactic acid) (PDLLA), giving better mechanical strength and thermal resistance.
High mechanical strength and stiffness – suitable for load-bearing temporary implants.
Good melt processability – can be processed by injection molding, extrusion, melt spinning, and 3D printing.
Renewable origin – derived from plant-based resources such as corn starch or sugarcane.
Tunable degradation rate – can be adjusted by molecular weight, crystallinity, and copolymer composition.
Transparent in amorphous form – can become opaque after crystallization.
Regulatory acceptance – certain grades are used in FDA-cleared or CE-marked medical devices, depending on application and grade.
