AI Technical Summary

Problems solved by technology

Among them, the low mechanical properties of aliphatic and aliphatic-aromatic polycarbonates limit their application in engineering plastics
In addition, its high melt viscosity limits its application as injection molded products
The processing temperature is high, and it is difficult to inject large-scale products. At the same time, because the molecular structure of the polymer is rigid, the internal stress of the product is large, and stress cracking is easy to occur.
