Continuous research and process optimization in synthesis, purification to polymerization of lactide over many years.

Technology introduction

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 chemical method through hydrocyanic acid and acetaldehyde, and then synthesis from polylactide to polylactic acid.

引领PLA技术变革,迎接可降解塑料时代

Technical advantages

◆ Whole process technology package about chemical method and new generation fermentation method of producing polylactic acid from lactic acid .

◆ More chance of selecting raw material route, the invest cost is lower and it has great advantage if polylactic acid is produced in large-scale.

◆ It has different series of product lines according to molecular weight and molecular weight distribution;

◆ Easy to develop new process about copolymerization and modification of polylactic acid.
