SABO™ PEI (Polyetherimide)

High heat resistance, dimensional stability, and chemical resistance.

PEI (Polyetherimide) is a transparent amber high-performance polymer with excellent dimensional stability and broad chemical resistance. It offers high strength, dimensional stability, as well as excellent flame retardancy and heat resistance. With a continuous service temperature of 170°C, PEI is an ideal choice for applications requiring consistent insulating performance across a wide frequency range. Its hydrolysis and chemical resistance enable it to withstand repeated autoclave sterilization cycles in the medical, pharmaceutical, and biotechnology markets.

Applications

Semiconductor

We provide high-purity, antistatic, and acid/alkali-resistant engineering plastics for precision components such as wafer carriers, packaging and testing equipment, and cleanroom accessories.

Aerospace

We specialize in lightweight, high-temperature-resistant, flame-retardant, and weather-resistant materials for applications such as cabin interiors, structural components, insulation parts, and precision aviation assemblies.

Automotive Manufacturing

We focus on lightweight, insulating, flame-retardant, and chemical-resistant materials for new energy vehicle battery, motor, and electronic control systems (three-electric systems), connectors, interior and exterior trim, and structural functional components.

Medical Devices

We utilize biocompatible, sterilizable, and hydrolysis-resistant medical-grade materials for diagnostic equipment, surgical instruments, and sterile structural components.

Energy Sector

We provide weather-resistant, insulating, corrosion-resistant, and high/low-temperature-resistant materials and structural components for photovoltaic, wind power, and energy storage applications.

Industrial Sector

We supply high-rigidity, wear-resistant, and self-lubricating materials for general components such as automation equipment, gears and bearings, pumps and valves, and fixtures and jigs.
