Features: 100% Brand new and high quality. It is made of high quality material, stable and durable. PEI sheets (polyetherimide) provide 3D printed surfaces without the need for tape, paste or glue. ABS and PLA stick to the surface very well and have strong grip. The temperature is stable at 150 degrees when you use it. Specifications: Material: PEI Standard: 120*120mm/4.72*4.72inch, 157*157mm/6.18*6.18inch, 235*235mm/9.25*9.25inch(optional) Color: As is shown on the photo Package list: 1 x PEI(include Back Glue) Note: Method of application: Please paste the back glue on the surface first, and then remove the transparent protective film before use.

This helps to clean the surface between prints with isopropanol, methanol or soap, ensuring that PEI is clean and promoting adhesion. Milled with 5000 sandpaper will also provide more life meters for PEI. 1、100% Brand new and high quality. 2、It is made of high quality material, stable and durable. 3、PEI sheets (polyetherimide) provide 3D printed surfaces without the need for tape, paste or glue. 4、ABS and PLA stick to the surface very well and have strong grip. 5、The temperature is stable at 150 degrees when you use it.
