Description

Medical grade PDLLA/PLLA/PDLA CAS 51056-13-9 polymers factory

PDLLA is a non-crystalline polymer, the appearance is white to light yellowish-brown irregular particles or powder. According to the end group of the tail, poly-DL-lactic acid is divided into three structural forms: hydroxyl-terminated, carboxyl-terminated and ester-terminated.

PDLLA is formed by the polymerization of DL-lactide. The product made of racemic polylactic acid has good biocompatibility and is used as a drug release carrier, the drug is embedded in a polymer which forms microspheres or microparticles.

Application

Medical grade PDLLA/PLLA/PDLA CAS 51056-13-9 polymers factory

PDLLA is approved by the as an auxiliary material and internal fixation device for corrosion inhibitors and injection microcapsules, microspheres and implants, it is also used as a porous foam scaffold for tissue engineering cell culture, bone fixation or tissue Tissue engineering of repair materials; surgical sutures, etc.

The biodegradability of the material allows it to be used for sutures for wounds. After the wound heals, the material naturally degrades. This characteristic also makes it an efficient drug delivery system, allowing for a delayed or continuous delivery.
