High Quality Polylactic Acid (PLA) with the CAS number 26100 - 51 - 6 is a biodegradable thermoplastic aliphatic polyester derived from renewable resources, such as corn starch or sugarcane. It is known for its high strength, stiffness, and transparency. The product is available in various molecular weights, which can range from low to high, offering different physical and mechanical properties.
Typical physical properties include a density of approximately 1.24 g/cm³, a glass - transition temperature (Tg) around 55 - 60°C, and a melting point of about 150 - 160°C. The high - quality PLA we offer has excellent thermal stability and can be processed using common plastic processing methods like injection molding, extrusion, and blow molding.
PLA has a wide range of applications due to its unique properties. In the packaging industry, it is used to make food packaging materials, such as trays, containers, and bottles. Its biodegradability makes it an environmentally friendly alternative to traditional petroleum - based plastics, reducing the environmental impact of waste disposal.
In the medical field, PLA is used for sutures, tissue engineering scaffolds, and drug delivery systems. Its biocompatibility and controlled degradation rate allow it to perform specific functions in the human body without causing significant adverse reactions. Additionally, PLA is also used in 3D printing. It can be easily printed into complex shapes, making it a popular choice for rapid prototyping and manufacturing customized parts.
Before using the PLA, it is recommended to dry it in a desiccant dryer at a temperature of 70 - 80°C for 4 - 6 hours to remove any moisture, as moisture can affect the processing quality and the final properties of the product. For injection molding, the barrel temperature should be set between 180 - 220°C, and the mold temperature should be around 20 - 50°C. The injection pressure and speed need to be adjusted according to the specific part design.
In extrusion processing, the temperature profile along the extruder should be carefully controlled. The screw speed and die design also play important roles in achieving a high - quality extruded product. When using PLA for 3D printing, make sure the printer nozzle temperature is set between 190 - 220°C, and the print bed temperature is around 50 - 60°C. Adjust the printing speed and layer height according to the desired level of detail.
Case 1: Food Packaging Company
A food packaging company switched from traditional plastic materials to our high - quality PLA. They used it to produce food trays for fresh produce. The PLA trays had better clarity, which allowed consumers to clearly see the products inside. Moreover, due to the biodegradability of PLA, the company's environmental image was significantly improved, and they received positive feedback from environmentally - conscious consumers. Sales increased by 15% within six months after the switch.
Case 2: Medical Device Manufacturer
A medical device manufacturer used our PLA to develop tissue engineering scaffolds. The scaffolds were designed to support the growth of cells in vitro and in vivo. The biocompatibility of PLA ensured that the cells adhered and proliferated well on the scaffolds. After successful animal trials, the product was ready for further clinical studies, showing great potential in the field of regenerative medicine.
Case 3: 3D Printing Service Provider
A 3D printing service provider used our PLA for rapid prototyping projects. They found that the PLA could be easily printed with high precision, and the printed parts had good surface finish. This enabled them to offer faster and more cost - effective prototyping services to their clients, leading to an increase in customer satisfaction and repeat business.
