What are PEI (Polyethyleneimine) used for?

Manufacturing of aircraft and rocket components, including steering wheels, air and fuel valves, interior cladding parts, commercial airline food trays and containers, semi-structural components, etc.

Boasting outstanding heat resistance and dimensional stability, PEI maintains consistent performance under extreme environmental conditions, guaranteeing the safety and reliability of aerospace equipment.

Engine components, fuel injection systems, high-temperature connectors, high-power headlights and indicator lamps, various sensors (air conditioning temperature sensors, effective combustion temperature sensors, etc.).

PEI features exceptional heat resistance, high mechanical strength and wear resistance, making it an ideal material for critical automotive parts and boosting vehicle performance and service life.

Electronic components, connectors, insulators, circuit boards, coils, flexible circuits, reflectors, high-precision optical fiber components, fiber optic connectors, optical assemblies for optical transceiver modules, and more.

PEI delivers superior electrical properties with stable dielectric constant and dielectric loss, plus excellent insulation capacity, rendering it an indispensable material for the electronics and electrical industry.

Medical equipment including stopcocks, instrument trays, sterilization trays, pipettes, dental devices; medical device parts such as bone implants, surgical instrument handles, trays, clamps, prosthetics, medical lamp reflectors, etc.

Thanks to its favorable biocompatibility and chemical resistance, PEI is a premium option for medical device manufacturing, ensuring the safety and effectiveness of medical instruments.

Transparent windows, sensor covers, optical components, etc.

PEI offers favorable light transmittance to meet the transparency requirements of optical parts. Its heat resistance and chemical resistance also support its wide use in optical applications.

Microwave bowls, cookware, oven utensils, food trays, steam cookers and other products.

With outstanding comprehensive performance and design flexibility, PEI serves as an ideal manufacturing material for various household goods, meeting consumer demands for safety, durability and aesthetic appearance.

Lab equipment for chemical laboratories, manifolds, containers and accessories for pharmaceutical processing equipment, as well as vacuum pump impellers, ground glass joints for distillers, etc.

PEI’s heat resistance, solvent resistance and flame retardant properties enable its vital functions in these fields and guarantee the safety and reliability of relevant equipment.
