Good Quality: We use 100% imported PEI raw materials, which are thicker and more used, Easily handle temperatures up to 130°C and perfect for PLA, PEEK, ABS. The process is upgraded so it does not affect any use of bubbles. PEI is very expensive compared to PET/PEO, but its good performance, especially high temperature resistance and stability are still ahead.
