PEI 4001

PEI 4001 is a high performance, colorable polyetherimide grade. It is physically amorphous and transparent with a straw tint. Exhibits a superior combination of mechanical, electrical, and thermal properties including wear resistance and reduced friction. Also exhibits durability, high strength and rigidity at elevated temperatures, long term heat resistance and dimensional stability. Provides outstanding processability and chemical resistance (hydrocarbons, alcohols and halogenated solvents). PEI 4001 is sterilizable by steam, X-ray and ethylene oxide. Creep resistance over the long term allows PEI to replace metal and other materials in many structural applications. Applications include head lamp reflectors, electrical components, oil & chemical service and medical instruments.
