Procuring the right grade of Poly(L-lactide) (PLLA) requires a solid understanding of its technical specifications. For procurement managers and R&D scientists in the chemical and pharmaceutical industries, deciphering parameters like intrinsic viscosity (IV) and molecular weight is crucial for ensuring optimal product performance. As a leading manufacturer and supplier of PLLA, we aim to demystify these specifications and guide your purchasing decisions.

The primary indicator of PLLA's molecular characteristics is its intrinsic viscosity (IV). Typically measured in dL/g, IV provides a relative measure of the polymer's molecular weight. Higher IV values generally correspond to higher molecular weights, which in turn translate to increased mechanical strength, toughness, and often, a slower degradation rate. For applications such as orthopedic implants or load-bearing medical devices, a higher IV PLLA is usually preferred. When you search for PLLA for sale, pay close attention to the listed IV range.

Molecular weight (MW), often expressed in Daltons (Da), is another critical specification. While related to IV, MW gives a more direct measure of the polymer chain length. Manufacturers like us provide a range of MW options, from thousands to hundreds of thousands of Daltons, to cater to diverse processing and performance requirements. For example, PLLA with MW between 10,000-100,000 Da is common for many medical applications, while larger MWs might be sought for specific extrusion processes.

The appearance of PLLA is typically described as white or yellow granules. While minor color variations can occur due to processing or additives, consistency in appearance is a good indicator of product quality. As a reputable PLLA supplier in China, we ensure our PLLA meets stringent appearance standards.

Understanding these specifications allows you to make an informed choice when buying PLLA. Whether your focus is on drug delivery, tissue engineering, or advanced medical devices, the correct PLLA grade is vital. We encourage you to contact us to discuss your specific project requirements. As a reliable manufacturer, we offer competitive PLLA pricing and expert technical consultation to ensure you procure the ideal material for your application.
