Black PEI
Black PEI is a flame-retardant, heat-resistant thermoplastic with excellent strength and electrical insulation, ideal for aerospace, automotive, and electronics.
Black PEI (Polyetherimide) is a high-performance, amorphous thermoplastic designed for demanding engineering applications that require exceptional strength, dimensional stability, and flame retardancy. Known for its outstanding thermal performance, Black PEI maintains mechanical integrity at continuous service temperatures up to 170°C, making it highly reliable in harsh environments.
At GD Prototyping, we deliver premium-grade Black PEI materials tailored for precision parts where strength, reliability, and thermal stability are critical. Its combination of high heat deflection, electrical performance, and processability makes it a top choice for engineers in high-performance industries.
