A PEI plastic rod and sheet in various sizes.

PEI Plastic

PEI plastic (polyetherimide) standard grade offers exceptional electrical, thermal & mechanical properties with fillers available such as glass fibers increasing tensile strength & dimensional stability. TECAPEI PEI plastic is suitable for environments requiring repetitive steam sterilisation & resistance from chlorine/caustic/acid chemicals. Wide service temperature range between -50°C to 170°C.
Excellent chemical & UV resistance, inherently flame retardant
High heat resistance, strength & electrical insulation
Stable over a wide range of temperatures

​​Food, Medical, Aerospace Grades​

​TECAPEI PEI Natural grade is FDA certified for food contact. TECAPEI PEI Natural & TECAPEI PEI GF30 (glass filled) is FAR 25.853 approved for aerospace applications. TECAPEI PEI is widely used in electronics, automotive, mechanical, medical & vacuum technologies.

​Additives & Modifiers

TECAPEI PEI GF30 is available reinforced with 30% glass fibres which offers higher rigidity, increased mechanical strength & additionally providing dimensional stability. TECAPEI PEI GF30 is used for components subject to high static loads in constant high temperature applications.


​Typically TECAPEI PEI plastic is used in electrical, automotive, aerospace applications such as: circuit breaker housings, non-combustible connectors, jet engine components, aircraft & automotive components, coils & fuses, heat exchangers & medical components.
