Notes for PEI injection molding
PEI has strong high temperature stability, even if the PEI is not enhanced, it still has good toughness and strength. Therefore, the superior thermal stability of PEI can be used to manufacture high temperature and heat resistant devices. PEI also has good flame retardant, chemical resistance and electrical insulation properties. The glass transition temperature is very high, up to 215C. PEI also has very low shrinkage rate and good isodirectional mechanical properties.
