ULTEM-PEI plastic material
PEI stands for Polyetherimide, which is also an abbreviation of Polyethyleneimine and Personnel Efficiency Index.
Polyetherimide, referred to as PEI  for Polyetherimide, is an amber transparent solid. It has inherent flame retardancy and low smoke without adding any additives. Its oxygen index is 47% and its combustion level is UL94-V-0 The density is 1.28 ~ 1.42g / cm3. PEI has strong high temperature stability. Even non-reinforced PEI has good toughness and strength. Therefore, the superior thermal stability of PEI can be used to make high temperature and heat resistant devices. It has excellent mechanical properties, electrical insulation properties, radiation resistance, high and low temperature resistance and wear resistance, and can pass microwave. PEI also has good flame resistance, chemical resistance and electrical insulation properties. The glass transition temperature is very high, reaching 215 ° C. PEI also has very low shrinkage and good iso-directional mechanical properties. Adding glass fiber, carbon fiber or other fillers can achieve the purpose of strengthening modification; it can also be composed of heat resistant polymer alloy with other engineering plastics, and can be used for a long time at the working temperature of -160 ~ 180 ° C.
