Pei sheet on glass. Pei polymer is extruded by ensinger in sheet and rod shapes using sabic s ultem resin. Made in the usa. Pei polyetherimide is a strong rigid plastic that withstands high temperatures and offers excellent electrical insulation over a wide range of temperatures. In filled grades the addition of glass fiber reinforcement coupled with ensinger s proprietary extrusion techniques provides users with a polyetherimide offering that has both greater tensile strength and rigidity while also improving dimensional stability.

Borosilicate glass abs and pla filaments along with many other materials print directly on to pei surface without the need for additional adhesives tapes or slurry. On one i purchased a sheet of 0 3mm thick self adhesive pei and stuck it down to the glass. Purchase a sheet of 0 03 0 04 0 75mm 1mm thick pei thinner can be used but it is more difficult to apply exactly flat to your surface.

Unfilled pei thermoplastic is translucent and amber in color with exceptional mechanical thermal and electrical properties. Single 1mm thick sheet installs quickly on top of existing flat build platforms e g.
