Poly(L-Lactide), often abbreviated as PLLA and identified by CAS number 33135-50-1, is a remarkable biodegradable polymer with a distinct set of properties that make it highly sought after in various high-tech industries, particularly in the biomedical field. Understanding these characteristics is crucial for optimizing its use in drug delivery systems, medical devices, and tissue engineering.

NINGBO INNO PHARMCHEM CO.,LTD. specializes in providing high-quality PLLA, ensuring that our clients have access to material with precisely defined attributes. PLLA is a thermoplastic polyester derived from lactic acid, typically appearing as white or yellowish particles. Its molecular weight can vary significantly, impacting its physical properties such as viscosity and mechanical strength. Typical properties include:

  • Appearance: White or yellow particles.
  • Molecular Formula: (C6H8O4)n
  • CAS Number: 33135-50-1
  • Intrinsic Viscosity: Commonly ranges from 0.3 to 5 dl/g, influencing its processing behavior and the mechanical properties of the final product.
  • Glass Transition Temperature (Tg): Typically around 60-65°C, indicating the temperature at which the polymer transitions from a rigid, glassy state to a more flexible, rubbery state.
  • Melting Point (Tm): Around 175-185°C, defining the temperature at which PLLA melts.
  • Biodegradability: PLLA undergoes hydrolysis in physiological conditions, breaking down into lactic acid, which is then metabolized by the body. This makes it ideal for temporary medical applications.

The controlled degradation and inherent biocompatibility of PLLA are central to its success in biodegradable polymer drug delivery and medical device manufacturing. NINGBO INNO PHARMCHEM CO.,LTD. ensures that the PLLA supplied meets stringent purity standards, with minimal residual monomer and solvent content, critical for pharmaceutical applications. By providing detailed technical specifications and reliable material, we empower researchers and manufacturers to confidently integrate PLLA into their groundbreaking innovations.
