PGA technology with complete set of technology and independent intellectual property rights.

Technology introduction

The process flow of polyglycolic acid in high molecular weight can be interpreted as follows:

◆ Synthesis of glycolide from glycolic acid or glycolate,

◆ Refining and purification of glycolide,

◆ Opening ring in polymerization, devolatilization and granulation of glycolide.


Powerful technology enables biodegradable plastic PGA.

Technical advantages

◆ Reactive crystallization technology is adopted, which is lower in reaction temperature and has less side reactions;

◆ The glycolide obtained has higher purity, stable properties ;

◆ High utilizing rate of reactants and low cost;

◆ Polyglycolic acid has narrow molecular weight distribution and stable properties;

◆ The dwell time is precisely controlled, and the product yellowness index is low.
