BP10968 OH-PLLA-COOR, High Molecular Weight Grades, IV ≥ 3 dl/g, Mw ≥ 480 kDa

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

OH-PLLA-COOR (High Mw Grade) is an end-functionalised biodegradable polymer characterised by its long polymer chains. With a molecular weight ≥ 480 kDa and intrinsic viscosity ≥ 3 dl/g, it delivers exceptional mechanical strength, durability, and a prolonged degradation profile. The structure, featuring a hydroxyl group at one end and an ester group at the other, provides a platform for modification and ensures its role as a substantial base material for formulating high-performance, long-lasting degradable materials.

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

1.         Polymer Science & Synthesis
- High-Performance Copolymer Backbone: Serves as a substantial macro-initiator or primary chain for synthesising block and graft copolymers where mechanical strength is critical, for instance, in constructing high-strength biodegradable medical polymers.
- Polymer Alloy & Composite Enhancement: Acts as a high-modulus phase in polymer blends or composites to significantly improve mechanical properties such as tensile strength and impact resistance, suitable for developing advanced composite materials that combine toughness with long-term stability.

2.         Advanced Materials & Formulation
- Structural Composites & Engineering Plastics: Used as the continuous matrix in fabricating high-strength, biodegradable composites for applications in automotive, aerospace (interiors), or durable consumer goods. Its excellent biocompatibility also provides potential in the exploration of composite substrates for long-term implants.
- Protective & Functional Coatings: Formulated into high-build, wear-resistant coatings or barrier films that require long-term environmental stability and controlled end-of-life degradation, also applicable to specialty protective coatings with extremely high demands for durability and biostability.
