What is PEI-polyetherimide ？

PEI Ultem : The properties of this plastic are similar to those of polyarylsulfone, but it also offers significant advantages. Polyetherimides exhibit excellent creep resistance at a wide range of temperatures and stable high operating temperatures. Also exhibit very good hydrolysis resistance and dimensional stability within that range of polyetherimide characteristics.

PEI plastics have the following characteristics: Stable high operating temperature (170 degrees Celsius), Good mechanical strength,Good rigidity, Good creep resistance at all temperatures, Good dimensional stability,Excellent resistance to hydrolysis (suitable for repeated steam sterilization), Good electrical insulation, Good radiation resistance, Good chemical resistance to chlorine and alkaline/acid cleaning agent.

PEI material series

TECAPEI – Pure PEI plastic

TECAPEIGF30 – 30% glass fiber reinforced PEI plastic

TECAPEIMT – PEI for medical use, biocompatible.

TECAPE Inatural (PEI) has high mechanical strength and rigidity, very good hydrolysis resistance and dimensional stability, and relatively high long-term service temperature.

TECAPEIGF30 natural TECAPEIGF30 is a PEI material reinforced with 30% glass fiber. Such materials have good rigidity, extremely high mechanical strength, very good dimensional stability and high energy radiation resistance.

Application of PEI:

Because of its excellent comprehensive balance performance, PEI is effectively used in the industrial sectors such as electronics, motor and aviation, and as a metal substitute material for traditional products and cultural and daily necessities. By using PEI instead of metal to manufacture optical fiber connectors, the component structure Z can be optimized, the manufacturing and assembly steps can be simplified, and more accurate dimensions can be maintained.

They are used in the automotive field, for example, to produce high-temperature connections, high-power lamps and indicator lamps, sensors for controlling the temperature outside the vehicle cabin (air-conditioning temperature sensors) and sensors for controlling the temperature of the air and fuel mixture (active combustion temperature sensors). It can also be used as a vacuum pump impeller resistant to high temperature lubricant erosion, a ground glass joint (socket) of a distiller operating at 180 deg C, and a reflector of a non-illuminating anti-fog lamp.
