Basic Information and Parameters

Our product, High Quality poly(l-lactide) with CAS number 33135-50-1, is a high - performance polymer. The chemical formula of poly(l-lactide) is (C₃H₄O₂)ₙ. It is a thermoplastic polyester with excellent biocompatibility and biodegradability. This product has a relatively high molecular weight, which endows it with good mechanical properties such as high tensile strength and stiffness.

The melting point of our poly(l-lactide) typically ranges from 160 - 180°C, and its glass transition temperature is around 55 - 65°C. These thermal properties make it suitable for a variety of processing methods, including injection molding, extrusion, and blow molding. The product is available in a white or off - white powder or granule form, ensuring easy handling and processing.

Uses of the Product

Poly(l-lactide) has a wide range of applications across different industries due to its unique properties. In the medical field, it is used for the production of biodegradable sutures, tissue engineering scaffolds, and drug delivery systems. Biodegradable sutures made from poly(l-lactide) gradually break down in the body over time, eliminating the need for suture removal. Tissue engineering scaffolds provide a three - dimensional structure for cell growth and tissue regeneration, and the biocompatibility of poly(l-lactide) allows cells to adhere and proliferate effectively.

In the packaging industry, it is an ideal alternative to traditional non - biodegradable plastics. Poly(l-lactide) can be used to produce food packaging materials, such as trays and containers. Its biodegradability ensures that these packaging materials do not cause long - term environmental pollution. Additionally, in the textile industry, poly(l-lactide) fibers can be used to make eco - friendly fabrics with good moisture - wicking and antibacterial properties.

How to Use the Product

When using poly(l-lactide) for processing, it is important to first dry the material to remove any moisture. Moisture can cause degradation of the polymer during processing, leading to poor mechanical properties. The recommended drying conditions are typically at 80 - 100°C for 4 - 6 hours in a dehumidifying dryer.

For injection molding, the barrel temperature should be set according to the specific grade of poly(l-lactide), usually in the range of 180 - 220°C. The mold temperature is generally maintained at 20 - 40°C to ensure good part appearance and dimensional stability. In extrusion processing, the screw speed and extrusion temperature need to be carefully adjusted to achieve a uniform melt flow.

Usage Case Studies

Case 1: Medical Suture Production
A medical device company used our poly(l-lactide) to produce biodegradable sutures. By carefully controlling the processing parameters, they were able to produce sutures with high tensile strength and appropriate degradation rates. These sutures were tested in clinical trials on patients undergoing minor surgeries. The results showed that the sutures provided sufficient wound closure strength during the initial healing stage and gradually degraded over 6 - 8 weeks, reducing the patient's discomfort and the risk of infection associated with suture removal.

Case 2: Food Packaging
A food packaging manufacturer adopted poly(l-lactide) to produce food trays. After optimizing the injection molding process, they obtained trays with good stiffness and transparency. These trays were used to package fresh fruits and vegetables. The biodegradability of the trays was well - received by consumers, and the trays effectively protected the food from contamination during storage and transportation.
