Excellent quality Polypropylene Fiberglass - high mechanical properties PEI- Unfilled, GF, CF for industrial products cover – Siko Detail:
Polyetherimide (PEI) is an amorphous, amber-to-transparent thermoplastic with characteristics similar to the related plastic PEEK. Relative to PEEK, PEI is cheaper, but is lower in impact strength and usable temperature. Because of its adhesive properties and chemical stability it became a popular bed material for FFF 3D printers.
The glass transition temperature of PEI is 217 °C (422°F). Its amorphous density at 25 °C is 1.27 g/cm3(.046 lb/in³). It is prone to stress cracking in chlorinated solvents. Polyetherimide is able to resist high temperatures with stable electrical properties over a wide range of frequencies. This high strength material offers excellent chemical resistance and ductile properties suitable for various applications, even those including steam exposure.
