30% Carbon Fiber EMI Shielding (conductive) PEI is a subcategory of Polyetherimide. The additative is added by weight during the manufacturing process. Its elastic modulus ranges from 2600 to 3300 MPa. Its flexural modulus ranges from 2500 to 2600 MPa. Its tensile strength ranges from 29000 to 34000 MPa at break. Its flexural strength ranges from 37000 to 45000 MPa. Its Izod Impact strength ranges from 1.2 to 1.6 J/cm. Its elongation at break ranges from 1 to 3 %. Its specific gravity ranges from 1.39 to 1.42. Its molding pressure ranges from 10 to 30 MPa.

Polyetherimide, also known as PEI, is a thermoplastic polycondensate. The most common trade name is Ultem. PEI is in many ways similar to PEEK, but is cheaper, less temperature-resistant and lower in impact strength. PEI resins are commonly used in medical and chemical instrumentation due to their heat resistance, solvent resistance and flame resistance.
Additional Information
Other common Polyetherimide (PEI) include Unfilled PEI, and 30% Glass Fiber Reinforced PEI.
