BP10974 OH-PLLA-COOH, High Molecular Weight Grades, IV ≥ 3 dl/g, Mw ≥ 480 kDa

OH-PLLA-COOH, High Molecular Weight Grades, IV ≥ 3 dl/g, Mw ≥ 480 kDa Description

OH-PLLA-COOH (High Mw Grade) is an end-functionalized, ultra-high molecular weight biodegradable polymer (Mw ≥ 480 kDa, IV ≥ 3 dl/g). Its long polymer chains and high degree of entanglement deliver tensile strength, modulus, and extended degradation timelines, comparable to the mechanical performance of some traditional engineering plastics. The preserved hydroxyl and carboxyl end groups provide handles for surface engineering, covalent bonding, and integration into composite systems, making it suitable for structurally demanding, long-term biodegradable applications.

Additional Information

Hydroxyl- and carboxyl-terminated high molecular weight PLLA represents the height of performance in the field of biodegradable polymers, combining the biocompatibility of traditional biomaterials with engineering-plastic-level mechanical properties.

Stanford Advanced Materials (SAM) has achieved stable production and batch-to-batch consistency control of such high-performance polymers through proprietary polymerisation technology and precise precipitation and purification processes for ultra-high molecular weight products, overcoming challenges in high molecular weight PLLA synthesis such as viscosity control and end-group retention.

With the advancement of regenerative medicine, high-end medical devices, and green engineering materials, there is a demand for materials that combine high strength, long lifespan, and complete degradability. SAM's high molecular weight OH-PLLA-COOH provides a material solution for these applications, facilitating the transition of high-performance absorbable materials from the laboratory to industrialisation.
