PEI Polyetherimide - Suzhou Mingrise Materials Technology Co., Ltd.

PEI Polyetherimide

PEI (Polyetherimide) is a transparent amber-colored high-performance polymer with good dimensional stability and broad chemical resistance. It offers high strength, dimensional stability, and excellent flame retardancy and heat resistance. Because this grade can operate continuously at temperatures of 170°C, PEI is an ideal choice for applications requiring consistent insulating performance across a wide frequency range. Its hydrolysis resistance and chemical resistance enable it to withstand the repeated autoclave cycles of the medical, pharmaceutical, and biotechnology markets.
