DiQi has the technology to prepare PLGA with different end groups, molecular weights, intrinsic viscosities, and monomer ratios (such as 50:50, 65:35, 75:25, 85:15, 95:05, 100:0, etc.), which can meet the development and industrialization needs of long-acting drug delivery formulations.

Poly(L-lactic acid, PLLA), also known as polyL-lactide and polyL-lactic acid, is formed by the ring-opening polymerization of L-lactate or L-lactide. Due to its good biocompatibility and controllable degradability, PLLA is widely used in orthopedic fixation materials, medical sutures, tissue engineering stents, medical aesthetic fillers, and other fields, and has passed FDA, NMPA, CE and other certifications.

Racemic polylactide/polylactide (Poly(D,L-lactide) (PDLLA/PLA for short) is formed by racemic lactate condensation polycondensation or racemic lactide ring-opening polymerization. PLA is a typical biodegradable polymer material with high mechanical strength, processability, biocompatibility and degradability, and is widely used in drug sustained-release carriers, soft tissue filler materials, 3D printing and other fields.

Polycaprolactone (PCL) is an important biodegradable material, with excellent hydrophobicity, flexibility, biocompatibility and controllable degradability, while showing good viscoelasticity and low-temperature processability, can be prepared into microspheres, fibers, films, foams and other forms, widely used in orthopedic implants, absorbable surgical sutures, drug sustained-release carriers, tissue engineering stents, medical aesthetic fillers, 3D printing and other fields, and has passed FDA, CE, NMPA certified.

mPEG modification materials (such as mPEG-PLA and mPEG-PCL) are a type of functional polymer materials formed by copolymerization or blending of methoxy polyethylene glycol (mPEG) and biodegradable polyesters (such as polylactic acid PLA, polycaprolactone PCL), which combine the hydrophilicity and biocompatibility of mPEG with the biodegradability and structural tunability of PLA/PCL, and have important application value in the biomedical field (such as drug delivery and tissue engineering).
