TECAPEI™ EF natural

PEI Bio-based

TECAPEI EF natural (PEI) is an unreinforced polyetherimide from our sustainable stock shapes solutions, designed for applications in a variety of industries such as healthcare, aerospace interiors, consumer electronics and food processing, among others. 

With a reduced carbon footprint, this biopolymer represents a greener alternative to conventional PEI polyetherimide material. The mass-balanced bioplastic offers equally outstanding mechanical strength and rigidity, with the property profile encompassing remarkable hydrolysis resistance and dimensional stability. Additionally, it ensures a comparatively high long-term service temperature.
TECAPEI EF natural is available as an environmentally friendly bio PEI stock shapes in the form of bio PEI plates and rods.

TECAPEI EF natural is part of Ensinger's "Reuse for Tomorrow" solutions, which includes carefully developed products that contribute significantly to environmental protection through their reduced carbon footprint.
