Product Introduction
Polyetherimide (PEI) is a transparent amber-colored amorphous thermoplastic specialty engineering plastic. Its English name is Polyetherimide, and its abbreviation is PEI. PEI's molecular structure contains both aromatic amine functional groups and ether structures. The aromatic ring and imide ring give it a rigid and anti-creep characteristic and high temperature stability, while the ether bond makes it have the flexibility required for thermoplastic molding. The density of PEI is 1.27 g/cm3, its glass transition temperature is 215℃, and its heat deflection temperature is 198-208℃.
