Polyetherimide

CAS: 61128-46-9
Molecular Formula: (C39H30N2O6)n
Molecular Weight: 0
Product description:Amber transparent solid, do not add any additives have low inherent flame retardancy and smoke, oxygen index was 47%, the level for UL94 burning - V - a level 0, density is 1.28 ~ 1.42 g/cm3. PEI has a strong high temperature stability, even if is enhanced PEI, still has the very good toughness and strength. Therefore using the PEI excellent thermal stability can be used to make high temperature device. With excellent mechanical properties, electrical insulation, radiation resistance, high and low temperature resistance and wear resistance, and can through the microwave. PEI has good flame retardant, resistance to chemical reactions, and electrical insulating properties. Vitrification transformation temperature is very high, up to 215 ℃. PEI has a very low shrinkage rate and good mechanical properties such as direction.
