Based on its strong technical strength in the field of Biochemistry and rich engineering experience in chemical unit operation, DODGEN has not only developed the process technology package of lactic acid to lactide by biological method and polylactic acid by ring-opening polymerization of lactide, but also developed the process technology package of lactic acid monomer with optical rotation structure by the chemical method through hydrocyanic acid and acetaldehyde, and then synthesis from polylactide to polylactic acid.
Whole process technology package about the chemical method and new generation fermentation method of producing polylactic acid from lactic acid .
More chance of selecting raw material route, the investment cost is lower and it has a great advantage if polylactic acid is produced on large-scale.
It has different series of product lines according to molecular weight and molecular weight distribution;
Easy to develop new processes about copolymerization and modification of polylactic acid.
