Description

PDLLA is an important biodegradable polymer material, characterized by non-toxic, non irritating, biodegradable absorption, high strength, good plasticity, and easy processing and molding. The degradation cycle is 2-12 months. The degradation cycle can also be changed according to the addition of different modifiers. PDLLA undergoes enzymatic decomposition in organisms, ultimately forming carbon dioxide and water, with good biocompatibility.

PDLLA material is one of the most clinically applied and FDA recognized polylactic acid degradable materials. Unilong Industry produced PDLLA is an amorphous polylactic acid polymer that belongs to racemic polymers and has no optical activity

Application

PDLLA has many uses, mainly in the medical and pharmaceutical fields such as surgical Surgical suture, dentistry, ophthalmology, pharmaceutical controlled release system, Artificial skin, artificial blood vessel, bone and soft tissue defect filler, bioabsorbable stent, etc.

Features and Benefits

Due to its good biocompatibility and degradability, PDLLA materials are widely used in the development and development of bone tissue engineering materials for clinical fracture fixation or bone defect implants. It is currently one of the most widely used synthetic biodegradable polymers in medicine.

Packaging

1kg/bag or 25kg/drum. All of the polymers should be stored at 0 ° C. Before opening, the product should be allowed to adjust to room temperature to avoid condensation polymer concentrate combined with moisture in the bag. To re-opened after the product packaging sealing, must be of high purity dry nitrogen filled to prevent moisture generated in the bag.
