D-LACTIDE Application
D-lactide as a polymerization monomer is mainly used for homopolymerization to obtain dextran polylactic acid. This homopolymer has optical activity, good stereoregularity, certain crystallinity and melting point, and good mechanical strength. Therefore, PLLA is commonly used in medicine to process bone screws and other orthopedic load-bearing bodies.
D-LACTIDE Storage
E- Avoid contact with water, acidic substances, alkaline substances and alcohol reagents, and other reagents that may cause product degradation during storage.
During the storage process, it should be sealed, dried and low temperature (freezer frozen -20 degrees), sealed with a sealing machine (the remaining products after use should not be stored in ziplock bags).
When using, take it out from the refrigerator and leave it at room temperature. After it is heated to room temperature, wipe off the condensed moisture on the surface of the bag before opening it. (If it is not opened under constant temperature, the moisture in the air will condense to the surface of the product. product will degrade). The air humidity of the environment should be less than 35% when used, to avoid moisture in the remaining products and affect the quality of the product.
