</br>YOTINO 12" x 12" PEI Sheet, Ultem Sheet, Adhesive Transfer Tape Sheets, 3D Printer Build Surface </br> </br>What is PEI (Polyethermide) </br>1.High strength and heat resistance (up to 340° F) allows the polymer to perform consistently in high temperature environments. When used in a 3D printing application, PEI is excellent because it can withstand the numerous heat cycles that a 3D print bed goes through from print to print </br>2.Polyetherimide has a natural Amber(yellow-orange) color and comes in different grades. Ultem 1000 is the standard, unfilled grade. It is inherently flame resistant and low in smoke production </br>3. PEI (Polyetherimide) sheets provide a 3D printing build surface that requires no tape, slurry, or adhesive. ABS and PLA both stick extremely well to the surface, which eliminates the need for support rafts used for better adhesion. The printed 3D parts will adhere to the PEI surface on a heated bed, and it will release or pop off when cooling down </br> </br>Features:1. PEI sheet is 3M tape pre-applied, which means you have no need to apply the 3M tape on the sheet anymore, and no man-made air bubble. </br>2. Easily clear the Ultem sheet surface with a quick wide done with isopropyl alcohol, methyl alcohol, or soap for next use. </br>3.You will be amazed at how well this sheet works for PLA and ABS filament adhesion if you buy the PEI sheet. </br> </br>Specification: </br>Color: Amber </br>Material: PEI (Polyetherimide) </br>Size: 12’’x12’’ (300*300mm)</br>Thickness:0.2mm/0.008 Inch </br> </br>Package Content: </br>1 x 12*12 PEI Sheet with 3M tape pre-applied
