Machined part

TECAPEI EF natural is an unreinforced, mass-balanced PEI (polyetherimide) semi-finished product. Renewable raw material sources are used in its manufacture according to the mass balance approach. The use of renewable raw materials is allocated to the product on a calculated basis; a specific, physically measurable bio-based content in the individual semi-finished product cannot be derived from this.

The material exhibits the properties typical of PEI and offers high mechanical strength and stiffness. It is also distinguished by high hydrolysis resistance and dimensional stability. Even at long-term high service temperatures, TECAPEI EF natural offers a comparatively high continuous use temperature.
The PEI semi-finished product is suitable for applications in healthcare, the aerospace industry, consumer electronics, food processing, and numerous other industries. Ensinger offers the PEI bioplastic made from mass-balanced raw material as plates and rods.

Compared with the corresponding fossil-based variant, TECAPEI EF natural has a lower Product Carbon Footprint (PCF). You will find the PCF values and the calculation method in the download area.

TECAPEI EF natural is part of Ensinger's ‘Reuse for Tomorrow’ solutions. These products support the reduced use of fossil raw materials.
