Description

D-Lactide is a polymerized monomer. It has low acidity and can meet the requirements for the preparation of high molecular weight polylactic acid. At the same time, it has high optical purity, and has good controllability of the crystalline properties of the final polymer. D-Lactide is mainly used for homopolymerization to obtain d-lactic acid. This homopolymer has optical activity, good stereoregularity, a certain degree of crystallinity and melting point, and good mechanical strength. Therefore, PLLA is commonly used in medicine to process orthopedic load-bearing bodies such as bone screws.

Packaging

As your requirements

Storage

This series of products are biodegradable materials. Avoid contact with water, acidic substances, alkaline substances and alcohol reagents and other reagents that can cause product degradation during storage.

 

This series of products should be sealed, dried and stored at low temperature (freezing at -20℃ in the refrigerator) during storage. They should be sealed with a sealing machine (the remaining products should not be stored in ziplock bags after use).

 

When in use, take it out of the refrigerator and leave it at room temperature. After the temperature is constant to room temperature, wipe off the moisture condensed on the surface of the packaging bag before opening it. The ambient air humidity during use should be less than 35% to prevent the remaining products from getting wet and affecting the product quality.
